1) make the "common configs" / "Advanced Config" sticky. I almost never find what I want in common configs and I'd just assume have it stay "advanced config" all the time.
2) implement some kind of history so I can easily go back and forth between components. I find I often want to go back to some other window click event, grab some code, then move to the click event I'm working on now. I find I'm doing a lot of pasting stuff into notepad right now.
