Running this through Proton on Linux for some reason left click with modifiers works fine but using just left click to get the items for one block doesn't work. Don't know if there's a separate way that the input checking for the modified inputs works (maybe a different API).

I understand this may not even be something you can fix on the mod's end, but I figured I'd make a post about it here for others who are also on Linux who may be confused about this issue. If it can be fixed, great! If not, it is what it is.
