[Cog]

Vital needs in order of importance:
Filtering (the current side search list is too narrow to be useful for me)
Clones
Tags
Multi-criteria SmartSearch Folders

Nice -but not necessary- touches:
Easy Manual highlighting (like CPNotebook -press a modifier and the cursor becomes a highlighter)
***** Ratings
Flagging
Linking to item from external applications

Pipe dreams:
Webkit/rtf/txt/pdf viewer built into comments field
live update linking to Omnigraffle (effectively providing a mindmap view)
