Here's a bug which is probably easy to fix, and reproducible.

Basically, I love Virtual Folders, so I use a lot of them.  I also like the
idea of virtual folders of virtual folders, and so when I organize my
VFolders, I usually have some large search (Parent) and then subsearches of
that larger search (Child1, Child2, etc.)... so that I may have VFolders in
this configuration:

Parent
|-> Child1
|-> Child2
|-> ...

However, the problem is that if I rename Parent to @Parent, the GUI for
folder display suddenly uncollapses the view of Parent's children.  In
addition, if I try to right-click Child1 to get Properties, it says the
VFolder does not exist (yikes!).

However, if I go into the Virtual Folder Editor, I see the problem clearly.

Child1 is named Parent/Child1, but it should be named @Parent/Child1.  If I
rename it, right-click actions work.

That's it, then!  If you need any clarification, just ask.
