I would also like to know.
Things I do not need in my list of MRU apps are:
Explorer
Auto-start apps (tray icons)
Apps I open with a desktop icon
I got really used to the behavior of another Start Menu replacer, where the Start Menu would would only show apps I specifically launched using the Start Menu. I have to keep removing items I don't want to be there every time they randomly come back. It's not a dealbreaker, StartAllBack is awesome. I just wish that things I did not open via the Start Menu would stop showing up in the MRU apps list.
