Project extension wizard, feature

Hi, all

I use CnWizards all the time. It's great!
However, I still can't give up Unit Expert addon (it's buggy and closed-sourced). It's just like CnWizards "List Units" functionality, but in a lot of more usable form - it searches through Search Paths for current project (relative paths also) and Environment defined paths. So Delphi unit must not be in project list.
Maybe honoured Cn-developers can make such valuable feature to "List Units"?

Thanks.
