Heres a list of ideas i thought would be good to add to the CCleaner program.
1. system restore point cleaner
2. hibernation log cleaner
3. components cleaner
4. webclient/publisher temporary file cleaner
5. compress old files cleaner
6. error log cleaner
7. option where you can choose a hard drive to clean
8. update feature so you can update from the program itself
9. thorough scan feature for both the cleaner and registery cleaner
10. feature that allows you to exclude a folder from scans
11. scanner that finds and removes unneeded files such as: copyright files, license agreement files, read me files, html files and other unneeded files like that.
