Undo/redo?

Hey, Thanks for this awesome tool! Currently I'm trying it out, and I was wondering whether it's possible to undo/redo actions? I'm unfamiliar with the properties that can be tuned (I don't know much about sound), so I just try them out, but it's quite time consuming to remember the previous value each time, then try tuning it, and then set it back manually. While I try to remember the original value each time, I sometimes forget. Alternatively, I could save each time I make a change, but then some sort of file versioning would be necessary, but it wouldn't be as easy as undo/redo.
