Save (versions of control schemes) and Undo/Redo

Given how much work it is to build even a simple control script (I'm using a Behringer X-Touch Mini), the application desperately needs to offer the ability to save my work on my demand with unique file names so that if something goes wrong, I can load a previous version.

Similarly, I have now lost hours of work because there is no UNDO feature. I accidentally deleted a controller I built (don't even know how that happened, not even sure I did it!). and now I have another hour of work to do just to recreate it. That's completely unacceptable for something I paid $90 for...

Highly frustrated.
