ipad undo should confirm

On an iPhone shaking to undo pops up a modal confirm prompt. This is bcs there's no room on the kbs for an undo key, but it's also the right way to do undos bcs if you do an undo accidentally, as one can easily on the iPad, which does not go through the confirmatory prompt, and then don't immediately redo you lose the undo memory,which may mean losing ALL your typing! To be clear, a redo after undo will save you, but if you've done an accidental undo then you are very likely to continue typing through it, and then the redo does not work! In fact, redo is sort of useless the way it is implemented now. In any case, undo should ALWAYS ask for confirmation!!
