Minor Mod improvements

[CharlesNicholas1999]

Absolutely love the work you have put in to port this mod to 1.21, it's probably the most useful thing in the game. Would like to make some minor suggestions to improve the usage. Don't feel rushed/obliged to implement these (as I feel like some of them might require a fair bit of tinkering) but would be nice.

1. For non-shulker inventories (crafting table, enderchest etc.) it would be nice for it to work when you have more than 1 of said item in your slot.
2. Adding a bind to pick block would be the best implementation imo as all the current binds have some other functions associated (I use shift + right click in itemscroller to move all but 1 item)
3. (This one's a stretch) It would be lovely if the mod is compatible with locked slots (from inventory profiles next)

Thanks!
