With several mods that use MaLiLib, the keybinds to open configs conflict with other keybinds by default, making it difficult to open the config to alter them ingame, as they don't show inside the vanilla controls menu. It would be nice if in the Fabric and Forge mod menus (Fabric using the Mod Menu mod) you could click the configure button to open a small GUI with buttons showing each mod that uses MaLiLib's configs, allowing access to them from the main menu.
Alternatively, letting MaLiLib configs be accessed through the config button in general would be nice, as currently any mod using MaLiLib has no configure option in the Fabric Mod Menu, unlike other Fabric config APIs.
It's just nice in general to be able to configure each mod through the Mod Menu, rather than needing to seperately press keybinds ingame to access each mod's individual config UI. I know manually editing the config files is possible, but it's much more pleasant to use a UI.

I have actually already implemented this for all the mods, but I haven't made new builds of all the mods yet since implementing that support. Looks like MiniHUD, Litematica and Tweakeroo have builds on my server (here: https://masa.dy.fi/tmp/minecraft/mods/client_mods/?mcver=1.14.4) that were made after implementing that support, but the only one of those that is on CurseForge thus far is MiniHUD.

I'm also considering other improvements to the config GUI stuff in my mods, because like you said the current method of having to use the hotkeys to open the config GUIs is not really user friendly or easy to use/remember for the general player base I imagine. So I'd like to have some kind of combined view/GUI for all my mods using malilib, in addition to the config buttons being in the Mod Menu GUI.
