This is the only way I know of contacting the mod so sorry if this is the wrong place but, I made some nicer looking UI elements and were wandering if you would like them?
I don't need credit or anything I just made them for personal use.

I don't know how to / if I can add the enhancement label and remove the bug one :p

You can create a resource pack with these icons, but I won't add these. I was requested by the hermits to use these specific icons. This is also the only purpose the mod serves.
