Feature request: working with groups of folders

Similar to my other request, it would be nice to be able to work on groups of folders in the left hand pane. For example, I have several folders with sets of rules to handle personal files, similarly for work and for managing my photo collection.
I have come up with a way to separate them visually using suitably named folders:

But it is kind of clunky.
It would be nice if there was a a built in separator that could be used.
Even better, it would be great to have a way to select one of these groups, or multiple folders, to pause/unpause them.
