def add an undo button &..

how many times to undo. I am having a bad glitch in saving a photo so ass support to your OWN programming mistakes if your going to keep returning customers, or even retain ANY customer to your products are this glitchy on large issues right from the start. If your going to LOOK like an editing program you must ACT like one IMO. Thanks and still playing with it even if I can't save it.
