One thing that _really_ annoys me about swipe-to-archive on gmail is that, if you do it accidentally, you can't swipe back to undo -- you have to actually tap 'undo'.

My muscle memory just seems programmed to swipe back in the direction I came; and this seems much more intuitive. It's such an annoyance that I've now disabled the swipe functionality.

Does Fastmail implement this better? Or maybe I'm just strange...
