Heyo everyone,

It's been another two months since my last update and I'm starting to like this tradition so here's another update on our Linux mod manager (also putting these out out of spite for the guy who said in my first post in January that I would only be working on the tool for two weeks and then give up 😏)

The update this time is a bit smaller because I had lots of personal stuff going on (moving, getting a new job, etc. etc.) in the past two months...

BUT!

We still have some exciting stuff to share so let's get right to it 😄

Switch modding

Added support for the Eden, Citron and Ryubing switch emulators
You will be asked for your preferred emulator during first time setup, and you can change it anytime from the settings
Keep in mind that NOMM only supports "standard" type switch mods (romfs/exefs) and does not support tool-specific mods such as Tears of the Kingdom mod manager's .tkcl format.

GameBanana support

GameBanana added as a source of metadata for manually downloaded mods (this means you can enter the mod ID in NOMM, and it will pull all the relevant mod metadata for you from GameBanana)
Added support for 1-click install for Switch games on GameBanana (needs to be enabled on GameBanana side, waiting for approval)

Bunch of QoL features and UI upgrades:

Mods can now be renamed to whatever you want
Games in your library can now be sorted by number of mods downloaded / alphabetical order
Mods in the mods list can be filtered depending on whether they are enabled/disabled
Icons have been completely revamped and are now bundled with the app (to avoid situations where certain DEs do not come with the icons that are used)
Can now go to the NOMM configuration directory straight from the settings
The settings also now has a little badge that will indicate the currently installed NOMM version and tell you if it's out of date / latest / dev
Added support for mod summaries (full descriptions can still be accessed by clicking the "+" when hovering the summary)

You can check out full patch notes on our Github.

As usual I want to end this little post with a call for aid from anyone who can spare a bit of time to test out the app and provide some much needed feedback. Last time we made a call out to see if someone could help us with testing Nexus collections support, and we didn't really hear back from anyone so if someone's interested in helping, please join us on Discord and ping us 😊

We are always reachable on our Discord server or on our Github.

It's been two months again since our last post and we have just released our biggest update yet (and this isn't just marketing-speak - it's a really big one) !

I've prepared some neat little patch notes for people who are interested in our progress, but we've definitely done some really nice progress and I hope you enjoy it.

Don't forget that we have a discord you can join if you want to join us and we have a Github!

(or you can also ask any questions you may want to ask here :) )

Mod Preview Pane (Allexio)

NOMM 0.10.0 mod preview pane

A brand new mod preview pane with a bunch of information and actions for the user to do. From it, you can:

Access the full description of the mod, locally viewable from the app
Access the Nexus page of the mod
See if there are new updates, and if so, to what version (and if a changelog is available, view it in app also)
Access & change the deployment path of the mod
See & access the uploader's nexus page
Endorse/unendorse the mod (and see current number of endorsements)
View/Modify the mod ID
- This lets you assign mod IDs to manually downloaded mods so that NOMM can query the metadata for you.

Completely overhauled FOMOD Support (Emetros)

NOMM 0.10.0 FOMOD Installer

We now have proper FOMOD support thanks to Emetros ! He has worked really hard on this feature and we both hope you appreciate the fruit of our efforts.

If you notice any cases that are not handled, please open an issue on Github.

Conflict Management (Emetros)

NOMM 0.10.0 Automatic Conflict Management View

When two mods modify the same files, NOMM automatically turns on "conflict management" mode which lets the user set a load order for the mods by drag and dropping in the UI to choose which mods will be overwriting the conflicting files.

If the user removes the conflicting mod, the app will automatically switch back to "simple" mode and remove the numbering & drag and drop grabbers.

Keep in mind this feature only checks the files actually present in the mods themselves (on the "surface level"). NOMM does not unpack game-specific files like for example .bsa files for Skyrim to check if different mods with different file names are actually conflicting over files that are in archives.

Flatpak Security Overhaul (Allexio)

NOMM 0.10.0 Permissions Request Window

Before this release NOMM basically had access to all your drives and the entirety of your home folder in read/write.

Now, NOMM is much more conservative when it comes to the isolation.

It starts with the absolute minimum rights to very specific folders such as the Steam or Heroic configurations. From there it reads the locations of your libraries and asks the user for access to those libraries via a command that the user themselves can read and validate.

You can read more on this topic on our new website.

Downloads management overhauled (Emetros)

NOMM 0.10.0 Inline Download Management

NOMM is now much more efficient & stable when it comes to downloading multiple mods at once. NOMM also displays a progress bar in-app when downloading a mod.

Steam Launch Options (Allexio)

name: Subnautica
steam_id: 264710
mods_path: "BepInEx/plugins/"

nexus_id: "subnautica"

essential-utilities:
  tobey-bepinex:
    name: Tobey's BepInEx Pack for Subnautica
    version: 5.4.23-pack.3.1.1
    creator: toebeann
    creator-link: https://github.com/toebeann
    source: "https://github.com/toebeann/BepInEx.Subnautica/releases/download/v5.4.23-pack.3.1.1/Tobey.s.BepInEx.Pack.for.Subnautica.zip"
    utility_path: ""
    steam_launch_options: WINEDLLOVERRIDES='winhttp=n,b' %command%

It is now possible to configure utilities to have Steam Launch Options.

These options can be automatically added by NOMM, but keep in mind that this requires Steam to be turned off.

You also have the option of copying the option when installing the utility.

Super experimental Nexus Collections download support (Emetros)

Emetros has implemented a rudimentary collection support, but we sorely need testers for this feature as neither he nor I have Nexus premium and therefore can not test the collections.

Brand new website (Allexio)

We have created a brand new website that will serve as wiki for the NOMM project.

The source code of the website is on Github and it is also hosted there for ease of maintenance & deployment.

New NOMM website homepage

The website features a description of NOMM's features, a user guide (including a guide on how to create your own YAML files for games you want to add support to), and specific game setup guides.

We also added new buttons on mod dashboards on NOMM to open the website wiki for that game if such a page exists (we only have a few pages for now, we need volunteers to write more!).

Arch Build (Emetros)

Starting with this release, it is now possible to generate an Arch package from the repo locally (see instructions in the README)

Flatpak will remain the "recommended" way to use NOMM.

General UI and various fixes

NOMM 0.10.0 GTK Theming Demonstration

Added tooltips to various buttons in the app to clarify their use
Redesigned the UI so it would better support GTK theming ( 🍚 ?)
A bunch of other things I can't remember because we delivered so much

Game support

Added support for various games (thanks stingflyer & Crasben)

I just want to emphasise how important it is for us to have community members involved in the project. We have a LOT of work to do on the app so for us it's either we develop new features & fix bugs, or we spend time writing YAML files & wiki pages for games we may or may not have. The choice is clear. These community members who choose to help us are absolutely vital to us and the future support of NOMM (and you get a special role on Discord :eyes: ).

100 stars on Github!

I also wanted to take a bit of time to thank our users (yes, even the silent protagonist types) who have tried our app and thought "hey, this has potential", and proceeded to star the repo on Github. This means a lot to us, and we hope you give the app another shot after this massive release.
