I kind of want something like markdown or WP reveal codes, where you can copy paste formatted text, but be able to see the formatting so you can remove anything unnecessary. There's countless implementations of formatting toolbars for web based editors, most of them bad, I feel like if operating systems handled this for users we wouldn't be wasting cycles on this kind of problem.
