Permission to use Zyin's HUD mod | Support | Forum

The biggest benefit of that mod by far is the option it gives to automatically unequip weapons and armor once they hit a certain percentage of durability (so that you don't accidentally lose an item because it hit zero durability when you forgot to manually unequip it when it got low).

I don't know if the ability to see horse stats could be construed as a competitive advantage over other players or not (isn't there a way to use f3 to view those anyway, or am i wrong there?), but that really is the only possible grey area i know of with that mod. It really is a nice hud mod, here's hoping it's allowed officially!
