I don’t want Runbox to copy others but what i really appreciated on Gmail was the “undo” button after the execution of some functions. It allows the user to roll back (a move from folder to folder, delete or even “recall” a sent message) for a few seconds after an “oups”.
Thanks for your suggestion – this would certainly be useful, but is not a small task as it would require logging such actions with all relevant details. I have added it as a low priority issue for now: https://github.com/runbox/runbox7/issues/184
