It would be useful to have an option to undo the reviews for a day. For example, if you set up a custom macro (eg. for a gamepad, etc.) that is designed with "...only give focus to the grading button" in mind, but had jpdb set to "...immediately grade a card" by accident, then you may accidentally pass a bunch of cards unintentionally, which you would want reverted.
Going back one page will undo the review, so you can just assign one button to the "go back one page" action, for example on linux the key code for that particular action is called "XF86Back".
