No, because both is not necessarily correct. You can create folders 
without specifying a parent folder.
No, we actually managed to get away from needing a root node in IMP 
4.1 even on systems that have this structure.



Rejected, because I don't think there is a nice solution that is less 
confusing than the current.

I was afraid fo that!



Could the menu text be changed from "Create folder" to "Create 
sub-folder here", and present an error if the user tries to create a 
folder without specifying a parent folder?



Is it possible to have the Folders view (optionally) display a "root" 
item which could be checked to create new top-level folders?



I'm trying to think laterally here, since the current interface is 
somewhat unintuitive.  Other ideas?

To be honest I find the new message even more confusing. It sounds 
like a warning but the user is yet asked for a folder name.

Our users get confused when they try to add a new folder -- the 
concept of "top-level" only makes sense to those of us who see the 
whole hierarchy (user.xxx, etc.).  I added an extra sentence to try to 
give users some idea of what they should do.  If someone has a better 
way to phrase this, I'm all eyes.
