That's exactly why I want a block feature while having a spell in my left hand. I can already do it now! All I have to do ist open up my favorites menu, unselect the spell from my left hand, close the favorites menu, block. Then after I blocked and/or hit/got hit I can turn around, press 3 for heal, heal, and then I have to open up the favorites menu again and unselect heal to be able to block again. Sure I'm using my left hand to block, I'm just looking for a mod that let's me just block without all that tedium! This doesn't work with spells. If you press the hotkey for a spell you already have in your left hand, it gets put in your right hand as well and after that it does nothing.
