Excellent idea on the first part. We're going through designs right now on how to better handle existing configurations. Will suggest mocking up something like that to the designers.
Regarding part two, I believe the eventual plan is to turn the Testing option in the wizard into the ability to scroll the entire button list and test every button. This should get you what you're looking for, code-wise. Further, our ultimate goal is to make most of this incredibly simple with just remote lookup, so you don't have to do any guessing at all.
