For new users and those who want to learn more, I would like to see exact definitions for all the file extensions JV16 identifies put in the manual, especially for the File Cleaner Tool. I like to make sure I know exactly what I'm doing before I delete anything.
I would also like to see the check box for "Unused shared OCX/DLL files" moved to the first page. (I got a shock to see all those weird files come up because I didn't notice the check box : ).
I love the suggestion of identification/explanations for entries in the Startup Manager.
