I'll see how much attachments I can fit in one post...
The first screen grab is MainMenu's interface. At the top you can see that it can do batch tasks. Second item in that same screengrab is the maintenance tasks we all know and love...
Second screengrab is the disk utility scripts...
Third is the rebuilding scripts...
Fourth screengrab is the various cleaning scripts...
Fifth screengrab is actions for the Finder...
Sixth is the rest of the tasks.
Hope this answers your questions and helps. Like I said, OnyX has more stuff like Unix scripts that I don't use anyway.
