I'd like to see the edit screen be at least as good as the add-post for existing thread screen. The new post and edit screens are given these teeny tiny editors, in a miniscule font, lost in a sea of buttons and ads. What this means in practice, is that I usually ignore my typing errors, because the edit system is too difficult to use. My HTF use is on an iPad in Safari. I don't use a desktop computer anymore for HTF.
