the other day I installed the mod for the first time, I already tried to look in my keybinds of my mouse to see if there was something wrong, everything seems ok but it still doesn't do what is supposed to do, doesn't sort and doesn't move items.
I am not sure what to do or what I'm doing wrong.

Sorry for the VERY late reply here, I'm new to the project and I'm trying to get on top of old issues.

Could you confirm if this is still an issue?
