The dual wield perks, coupled with the elemental fury shout, can get your melee attack speed up really high, to the point where it becomes a serious clickfest, especially with daggers. What I was thinking would be cool would be an alternate input scheme where single clicking performs a single normal attack. Double clicking performs a power attack. Holding the attack button causes you to automatically swing your blade repeatedly as fast as is possible, like an automatic weapon. Playing as a dual wielder I found myself using power attacks almost exclusively because of the amount of clicking involved, it would be nice to be able to sustain decent damage, conveniently, while saving my power attacks for when they're really needed (not that tactics are really important once you've reached a reasonably high level and are absolutely murdering everything in your path, but it might come in handy once Bethesda or mods nerf melee damage.)
