I've used Jellyfin for years now, but never got into themes. So I decided to make one that keeps the layout I'm accustomed to, but gives a few QOL upgrades. It's basically a dark mode theme. I worked a while on this so I decided to share it now that it's done.
(Made on version 10.11.11.)

Most notable changes is having a frozen nav bar a the top when scrolling. And better adjustments on the details page to show more of the Backdrop posters. There's a ton of other minor changes as well, but those are my reasons for creating these.

Edit: Forgot to mention that these work best on the Web browser and the Android app. The Windows app falls short of some of the features. And I haven't tested on any other devices.

I wanted to share a personal project I’ve been working on called AniList Manager.

I started this after the recent anime site takedowns. I imported my MAL list to AniList so that I could import into other places. I found that I lost a lot of stuff during migrations such as ratings or items in outdated lists. I needed a way to quickly review a show and set the list it should be part of. That one need is how this started.

I've been using this in leu of creating watch lists on the various sites that are out there. Only downside I've seen is the watch progression must be manually adjusted. And direct links to other sites must use either the AniList ID or MAL ID in the URL to work properly.

It is a personal project, made completely with AI, and is completely free to use. If you don't like that, then please ignore this post. 😄

EDIT: New Update supports Update Checking.

======= v1.1.0

• Added GitHub update checks so the app can detect newer portable releases from About and Settings.
• Check release notes for additional items.

What it is

AniList Manager Portable is a Windows app that runs locally on your PC. It starts a small local server, opens a browser UI, and lets you manage your AniList anime lists.

It is portable, so there is no installer. Download the ZIP from GitHub Releases, unzip it, and run:

AniListManagerPortable.exe

The app opens at:

http://localhost:6767

Main features

• Browse AniList lists by status:
  • Watching
  • Planning
  • Completed
  • Paused
  • Dropped
  • Repeating
• Update watched episode progress
• Update AniList scores
• Move shows between lists
• Remove entries
• Search and sort your list
• Add anime from AniList search
• Local notes support
• Sub/Dub availability badges when lookup data is available
• Watch Now / Details links with configurable anime site URL templates
• Offline Mode for packaging list data and cover images locally
• Appearance settings with light/soft/dim/dark/system modes
• Portable local data folder

How to use it

1. Download the latest ZIP from the GitHub Releases page.
2. Extract it somewhere on your PC.
3. Run AniListManagerPortable.exe.
4. Open Settings.
5. Add an AniList token.
6. Start managing your lists locally.

The README has more detailed setup instructions, screenshots, and notes about how local data works.

Privacy notes

The app runs locally and stores its data beside the executable in a data folder. Your AniList token is not sent to a remote app server owned by me. The browser UI talks to the local app running on your own machine.

I collect no data or send information outside of your browser with the exception of anime data lookup and API calls that are documented in the README.

A note about AI

This was made as a personal experiment/project using AI coding help from start to finish. I’m not presenting it as some polished commercial product. It is something I wanted for myself, and I figured other AniList users might find it useful too.

Feedback, bug reports, and feature ideas are welcome.
