Thanks for a great program.
My suggestions.
1. Alphabetize Start menu & favorites menu (like Supercleaner( http://www.southbaypc.com ).
2. An option not to delete all files it find during a search, just to see how much space I can recover(like Supercleaner( http://www.southbaypc.com ).
3. An automatic update/patch function, similar like 'FMA ( http://fma.sourceforge.net ).
4. A simple systemmenu with information about the system, freespace, regfile size......
Good luck
