Shout: Unrelenting Force
This way, all shouts are together on your hot key list.
And that's it. Honestly, that one little change would go a long way toward making Shouts more fun to play. As it is now I actively try and play without them, since finding them on a well populated hot key list is sadly so difficult and confused an endeavor as to take away from the fun of combat.
Thanks Bethesda for the game. I hope this small change is something someone can make happen in the near future.
