Actually I was refering to 'virtual' folders in a c::b workspace, in which I can add stand-alone files or c::b projects.
Yes, C::B supports that. Just right-click on the project and inspect the menu... ;-)
Probably my own stupidity, but I still do not get it. As seen in the picture I posted above, I want to create a virtual folder (as a direct child of the workspace, not a project), whose children are projects. I do know that there are virtual folders in projects, but I need the same functionality in a workspace.
On right-clicking on Workspace, I only get these options:
Rename workspaces...
---------------------
Save workspace
Save workspace as...
---------------------
Find File...
---------------------
Close workspace
