Fences is a brilliant idea and a very good product.  I look forward to using the professional edition.  One issue though is that as good as it is to have your stuff be organized and turned into a usable workspace, when you open up Explorer or any other file manager that organization turns to soup.  So if I have 20 cpp files in a project pluse 30 image files for a separate project, I go right back to hunting and pecking for the right file when trying to use an 'open' dialogue.

Why not extend the organization idea to explorer itself?  You've already got Libraries in Windows 7 that want to string stuff together.  Why not create a way for a "fences"/"desktop" library to be used from open dialogues.  That you need to have an actual directory to create a library subheading is irrelevant.  Because fences is brilliant and cannot be stopped. <nods>

Or something along those lines.
