I have to agree here.
I had an awful hard time to make such system for Countdown Live 2.0, since the script structure completely changed. Removing files in the Images folder is very easy, but script files are lots harder. Even with the actions taken, a script restart is still required in order to unload the obsolete script files. Luckily this should only be done once.
Patchou really needs to implement something so we can control what should be removed.
