Currently, instead of having a dedicated config folder for custom fabric mods that you add in the lunar launcher, all of your mods' config files are dumped in .minecraft.
This makes it quite a hassle to config any mod that doesn't have support for Mod Menu, and also causes problems when you use the same mod on two different versions of Lunar, since they share a config folder. I would suggest adding a button in the launcher that will open a dedicated folder which contains the configuration files for your additional mods.
