So, not sure if this may be a conflict with inventory tabs or something but anytime i try to use the "stack to nearby" inventory button, the whole client crashes, doesn't seem to matter if it's on server or single player.

thank you for the solution! i hope ya come up with something eventually though

This mod conflicts with Smooth Swapping. You can use shortcut keys to perform "stack to nearby" without opening the inventory screen so that the client will not crash. You can also use a modified version of Smooth Swapping that should work fine with this mod. I'm still looking for a better solution to make these two mods compatible.

Smooth Swapping mod after 0.8.1 no longer conflicts with this mod.
