This will happen if the parent Collection's content mimetypes contain 
Collection::virtualMimeType() - in other words if the parent collection 
indicates it can contain virtual collection, a virtual collection is created 
by default.

Since I believe you do not need virtual collections in EteSync, you can 
probably remove the content mimetype and "Add folder" should always create a 
non-virtual Collection.

At this moment I don't think it's possible to distinguish this. Sounds like it 
could be a nice small improvement to KOrganizer.

You could implement the dialog in a way that it recognizes whether it's a 
first-time configuration, which switches it to some sort of a "wizard" mode, 
where you get to input server URL, username and password on one screen, click 
"Next" and, after some background communication takes place, shows a screen 
where to enter encryption password. On the other hand if the dialog knows it's 
already configured it would show everything on a single screen as most other 
resources do now.
