The undo and redo button

[Pianobrak]

Is there a "redo" button as well as an "undo" button? I only see an undo button, Which seems to take you back to where u were when you last clicked save, instead of just undoing the last action. This is not a normal undo function in this way. Most importantly, is there a redo button?? Thank!

At which platform are you at? There is "redo" and "undo" in the OS X version. The "undo" goes back one step (your last action). There is no "redo" button in the iOS and Android versions. Let me know where you experienced the problem.
