1. Tinkers Canisters. The slot which holds tinkers heart canisters will not accept more than one when clocked on with a stack. The only way around this issues as my shift clicking in the canisters all at once.

Awesome mod. Keep up the good work!

1. the gui is configurable. Just move the level bar where you want it.
2. I'll look into it.
