There is no mod icon for modmenu. Maybe add the same icon as the icon you used on modrinth?

Fixed in version 2.0.5 (I just forgot to close this).

Maybe like this?

I'll look into adding an icon when I make a new release; I probably won't use any of the "usual" images, since they would drastically increase the size of the jar (currently 86 kB). My current idea is to use the hysteresis curve of a ferrite core which should compress much better, but I'm not entirely sure yet. In any case I won't make a release just for this, so it won't happen until someone either finds a bug or I (or maybe someone else) find(s) a new optimization to implement in FC.
