Accurate and flexible block placement modes are clunky to use.

[1schlick]

I don't like having to hold down a specific button combination for each placement mode. It becomes especially awkward when I'm trying to move around or hold the shift button while placing blocks using one of the placement modes. I have to stretch my hand across the keyboard in weird ways and. I would prefer to just hold down some hotkey and then scroll up or down to switch between the different block placement modes.
