draft deletion interface difficulty on touchscreens
On mobile/touchscreen interfaces (I assume this isn't a unique problem with safari on ipad at least) it's pretty hard to delete drafts, since the tiny little x button only appears when you mouse over a saved draft on the list and with a touchscreen there isn't an equivalent to mousing over things without clicking that I am aware of. Not sure if the x exists but is invisible or doesn't actually exist before you mouse over, but you can get it to appear if you tap in that area. The problem is that touching in that area is also a link to the thread the draft is from, so the only way to delete drafts is to mash around where the button will appear so that you hit the x and change what link you're trying to process to the "delete draft" one before it sends you through to the thread.
It's not a huge deal, and I get the impression the draft system is very low priority, but I thought I should at least mention it.
