PolyMC VS pacmc

No, not really. No one was in charge at the beginning. It was a community project with multiple people having the administrative role at the same time. LennyMcLennington was one of the contributers, but not really an important one. But he removed the administrative rights from the actually important people. Devs like flowln and Scrumplex played a much bigger role. Even after half a year being the only developer at the PolyMC-Project Lenny still heasn't caught up with what other conributers had done in a few months before.

Could I suggest trying a different launcher such as PolyMC? You can get this on deck in Linux linkand sign into your microsoft account to access Java. This version also has the benefit of you being able to get modpacks.

It's still open source, the repo hasn't moved. https://github.com/PolyMC/PolyMC/

The issue is: the main developer freaked out, made a post ranting about political bs, kicked everyone from the GitHub project and now it's been 2 months since it hasn't been updated. The developers who used to contribute to "PolyMC" moved from the "PolyMC" project to the "PrismLauncher" one after the drama.

There was no prompting or provocation towards lenny at all. The code of conduct existed for ages before lenny deleted it on oct 17 2022: https://github.com/PolyMC/PolyMC/commits/358f080c76dbdfc65f32e08448a5e38b78d2bab0/CODE_OF_CONDUCT.md

for polymc literally yes git commit (got deleted but title is there)

First, it's gio that handles trash in SteamOS. Second, after digging into PolyMC's code, it also leverages trash. Was added roughly 7 months ago in this commit: https://github.com/PolyMC/PolyMC/commit/02f30de1c11fa53e61c199032a3280afe618e3b2

It invokes that native file picker dialog on each platform, currently supporting Android, and Desktop (Windows, Linux, osX) using lwjgl and thanks to the work in the pacmc project.

Kotlin/JVM: LWJGL has native file dialog (NFD) bindings, here is how I used them with fallback Swing file chooser with native look and feel.

There are some open source launchers with that feature. I think at least Gdlauncher and Atlauncher have built in mod management (and probably instances as well). But I prefer to use a package manager for MC mods called Pacmc. It is not super fast like Pacman, but it works really well for managing MC client or server mods (I use it for both). The only features its missing for my use cases are disabling automatic dependency management and installing mods that are not marked as compatible with latest minecraft versions, but work just fine. Also it seems like the author of Pacmc is working on a gui right now.
