Please add an 'undo' button to Forms Designer. It is so frustrating to create a form, almost be finished, and then you do something that completely messes it up. Instead of having an undo button, I have to continue to try and fix it, which normally in turn means that I just make an even bigger mess and end up having to delete and start over.
Yes, I do copy my initial layout, but it's not until after I have messed up that I realize I need to start over. By then, it does no good to save where I am because I only make it worse.
