Add "undo" feature

Please add an UNDO feature to the Android version. It has happened to me multiple times that when trying to scroll (esp in the bus) it registers as a swipe & deletes a message. and then it's really hard to scan the trash to figure out which message it was at the same time, i don't want to be asked for confirmation *every* time i delete something - I'll spend as much time "confirming" as deleting messages. So the ideal in an undo button somewhere in the interface where a can undo the last action (from a subset, since I'm guessing not every action can be undone). The desktop version has it, hopefully it can be migrated to the android version. thank you Alvar
