Currently GuiOverlayEmotes has a hardcoded set of groups, it would be handy to have a proper way to add buttons for custom packs (as well as groups list scrolling).

I got it to work using ActionPerformedEvent.Post and InitGuiEvent.Post with some reflection, but it's way too hacky.

Closing since the mod is no longer supported and will be rewritten once ported to modern Minecraft version.
