TYPO3 Core

When editing records the Undo/Redo button which is a part of the panel of buttons for saving/closing a form etc. can usually be clicked and it will revert to previous state of record. Currently this links to the history module but stays there instead of reverting and redirecting back! This must be a bug Sebastian introduced during his re-wamp.
And talking about the history module: Its just fine with all those nice selectors, checkboxes etc. but there must be a simple, intuitive button like before which one can click to revert. I was desperately looking for a "commit" button somewhere after having selected, click etc on diverse buttons and seen nice previews of this and that - but the simple button was missing. We need that pencil with the arrow back in!
