Feature Request: expand shader downloader

[zany130]

Hello! First off, thanks for the great plugin — I’ve been really enjoying using LetMeReShade.

I’ve previously contributed a bit to ReShade-related logic in SteamTinkerLaunch, and one feature I found especially useful there was shader repository discovery/management.

Currently, LetMeReShade already allows installing a few predefined shader repositories during setup, which is great. However, I noticed a couple limitations:

1. Shader repositories don’t appear to be updatable once installed (please correct me if I’m mistaken)
2. The available repository list is fairly limited

In SteamTinkerLaunch, there is logic to dynamically fetch a list of ReShade shader repositories (e.g. from PCGamingWiki). I recently worked on improving part of that logic here:

https://github.com/zany130/steamtinkerlaunch/blob/master/steamtinkerlaunch#L9156

I was wondering if something similar would be in scope for LetMeReShade — specifically:

• Expanding the repository list dynamically (rather than relying on a fixed list)
• Reusing the existing install pipeline, without changing the current UI/flow

If this aligns with the project direction, I’d be happy to try adapting/porting the discovery logic to fit LetMeReShade’s structure.

Thanks again for the project!
