So I sideload most of my books onto my Kobo (including purchased books) because I primarily read on KOreader. I have noticed however, that normal purchased or borrowed books on Kobo (which I assume are in kepub format) the covers display normally in My Books. However, any sideloaded (imported) books' covers (which are all epubs, not kepubs) seem to have a fixed aspect ratio. It looks to be a 3:4 rectangle. Which wouldn't bee too much of a problem, except that most of my book covers are in a roughly 2:3 aspect ratio.

In Calibre, I try to "Polish" most of my books so that the covers look correct. For the books I haven't polished, the cover images kind of sit inside the 3:4 rectangle, in their original ratio, but smaller. For the Polished books, the covers fill the whole rectangle, but again, because they're mostly 2:3, they are squished and stretched.

Again, I don't use the native Kobo software THAT often, so it's not a huge deal, but it is quite annoying to look at. Is this just how Kobo displays epubs and there's no way to fix it? Is there some setting I can change? Is it perhaps Calibre itself doing this?

If it can't be fixed, no big deal, but if it can, that would be nice. Thanks for any tips!

My recreation of what I mean:

I switched to Firefox over a year ago now, and I'm generally happy with my experience, but man the History is awful. I use the History function a lot, and it being basically useless is very frustrating. I really don't understand why it only shows the most recent visit to a URL. If you visit it again, too bad! It's sooo fucking annoying.

Any time I think "hm, did I read/watch this already?" and go to check in history it only shows me when I literally just fucking opened the page. If I opened it last month, oh well! That's gone forever now. You wanted to know what day you opened this page back in March? Why? You just opened it 4 minutes ago. Surely you only want to see that right? And the stupid "Number of Visits" counter just mocks me. I don't understand this. Chrome and Opera and Edge were perfectly capable of storing history information in a normal and sane way.

Genuinely who is this feature for? Who wants every visit to a website to overwrite the previous visit? What's even the point of history then? Why did they need to combine the History with the Bookmarks Library?? Seriously, it just makes the History useless.

I made the switch to Firefox after they finally added a function I use often (tab groups) a couple years ago, especially when it was around when Chrome banned uBlock Origin. So i hope the devs get around to fixing this feature. Otherwise it's a perfect browser.

Unless there are any fixes to this? That allow you to see history in a way similar to Chrome history (shows you the date and time of EVERY visit, instead of the date and time of only the MOST RECENT visit and then a visit counter...)

EDIT: Okay so there appears to be some confusion about what I mean. So here's an example from Chrome History. Notice how "rivers 'til i reach you - Chapter 3" appears 3 separate times on 3 separate dates?

VS Firefox in a similar situation. You can clearly tell I read this at some point in November 2025, and then started it again at some point in May of 2026, but it only Shows Most Recent Visit in the History.

There's a lot of discussion about Jason and "Pit Rage" (which I believe is real but incredibly exaggerated and prolonged in fanon) and the psychological effects of the Lazarus Pit. Usually using Ra's al Ghul as an example of what the Lazarus Pit does to a person. While "Pit Rage" is used extensively in Jason Todd-centered fanworks, he was only exposed to the Pit once(?). And those who say Pit Rage is not real, usually attribute Ra's instability to the fact that he was exposed, repeatedly, for centuries instead. (And being alive for centuries probably also significantly contributes to whatever is wrong with him.) There are some other characters who've taken a dip once or twice, like Bruce (I'm pretty sure Superman threw him in there once or something right?) with no real effect. And surely something would be more wrong with Talia?

But it's shown in comics at some point that Damian was most likely exposed repeatedly to the Pit growing up. His training was brutal and he probably got significantly injured often and they used water from the Lazarus Pit to heal him, even restoring entire organs. Or at least, I assume it's a common occurrence, because in the panel I'm thinking of, Talia orders them to fix Damian up after he nearly dies so casually like it's a common occurrence and they have backup organs for him just sitting around? It's a combined magic-science surgery where they're using both medical equipment and (possibly diluted?) Pit water.

If anyone would have "Pit Rage" I think Damian is a good candidate especially with the psychological effects on a developing mind. I personally haven't seen any but I've only read a handful of Damian-centric fic. I mean he's already an angry child. I just feel like the fandom could do some interesting stuff with it!

[FIXED(?)] I synced my Kobo, returned a library book, and resynced it. Then I scrolled through my books. And then when I plugged it back in, suddenly the books registered. Even though I had restarted the device and resynced it multiple times before... I don't know, but it fixed itself I guess.

Hello, I've been having a semi-frequent problem where books that are on the device, don't show up in the "Show books in main memory of device" when the device is plugged in. (Which also means that books in my Calibre library are saying that they are not on the device.) This means I can't even "Match book to library" because...they don't even show as only being on the device. This also means that they are not added to the Calibre metadata (which as I understand, mainly matches the book in library to the book on the device) because again, doesn't even register that the book in on the device.

Is there a way to force Calibre to re-examine the device memory and check for books it missed?

Example in images. (Perks of Being a Wallflower is one of about 12 books that have this issue)

So I recently updated Simple UI and enjoying all the new features and the better settings menu. I noticed the (new?) To Be Read module you can add to the home screen. I added it but it's blank because I have no books in my To Be Read list...except, I can't figure out how to add books to the list? The only place I can even find mention of To Be Read is in the module settings where it says that the list is empty.

Any help with this would be appreciated. Thank You!

Hello! I've been using KOreader since May and I have been enjoying exploring the plugins and customization, but I have one issue that's a bit annoying.

I have Bookshelf, and I like the look and the way it displays information, etc, but...the series information is wrong. I edit the series information in Calibre before I ever load the books onto my device, and on KOreader itself the series information shows up correctly, but for specifically Bookshelf it's not correct.

If the epub file came with NO series information and I had to add it, it shows up correctly.

If the epub file came with WRONG series information and I had to correct it, it shows up correctly.

But if the epub file came with UNNECESSARY series information and I removed it, it shows up incorrectly. The series information that I removed is still showing up in Bookshelf.

This is annoying because most of the time, I remove the series information for fanfiction downloaded from ao3. If you've been around ao3 for a while, you know that occasionally the series isn't used for a series of fics in the same story but for collecting challenges ("Whumptober 2021", "Reverse Bang 2018"), or author's collections ("All my College AUs", "Fics where I kill off the parents for no reason lmao"), or for extras (missing scenes, alternate endings, or fanart showcases), or just unfinished (author created a series because they planned a sequel but never ended up writing it).

There are maybe 30 actual series between my books and fanfics, but it's showing up in Bookshelf as like 50.

Is there any way for it to read the series information correctly? Is it a case of the series information that I fixed only being like Calibre metadata? And Bookshelf uses the embedded metadata?

I have latest version of Book and KOreader.

Thanks!

Hi! I bought a Kobo Clara Color back in late April and I got the official Origami Sleep Cover along with it. It's been about 2 months, and I have become concerned about the protectiveness of the case. Where it folds is very thin and you can literally touch the screen through it. It doesn't feel protective enough for what I know is a fairly fragile ereader screen.

I have mostly been home so I didn't worry about it, but my job is hybrid and for summer I will be finally going in person (I've been WFH since October 2025). Since I will be out of the house more and plan on taking my Kobo with me (I have been reading SO much. Like almost back on the level of when I was in elementary-middle school. I used to read nearly a book a day. Definitely like 4-5 a week. And yes full books, like To Kill a Mockingbird, Hunger Games, Percy Jackson, Farenheit 451, a ton of YA novels, etc. I would occasionally knock out 2 in one day. I was insatiable.) I want a case that's more protective.

I'm in the US and since I paid $30 for the sleep cover, around that price is good for me. If it's really good my budget goes up to $50 to be honest. And I would prefer a cute color, but tbh understandable if the really protective ones aren't. Amazon, Etsy, or other websites are fine.

I've had a Kobo Clara Color for about 3 weeks, and yesterday I decided to try out koreader, because the customization and add-ons seemed really useful and nice, and I don't really buy books directly from the Kobo store anyway. I usually use calibre to load books onto my device, and since I did a factory reset before installing koreader, I had to reload all my books back onto my device.

This seemed fine and dandy, but when I opened calibre again today to maybe add some other books, and plugged in my kobo, it showed that my device had no books. When I opened up the file explorer to see if they got deleted, it showed that every single epub I loaded onto my Kobo now has the extension "kepub.epub" so calibre doesn't register them as the same file anymore. I usually don't convert the epubs I download into kepubs, because I don't really care and I'm not sure there's a difference (?) but I did not do this. It's very annoying.

Is there something that just automatically converts them??? And can I turn it off??

I have latest version of koreader, Simple UI plugin, and Bookshelf plugin, and that's it, except for a patch that adds a second status bar as a header (I recreated the native Kobo status where it shows chapter number/title and pages left in chapter at top, and book title and pages left in book at bottom, because I like it a lot)
