Allow the grouping of sequences within a sequence file

In order to logically sort sequences within a sequence file, you have to add either a prefix to your sequence names or add dummy sequences between sequence groups:

  

What would be great is if I could could add sequence groups which let me organize my sequences logically in a tree view. Unfortunately, I can't shoop my vision of that at the moment.

I had posted something similar but for  grouping variables.

Just to illustrate the idea, as I see it:

That would be a similar feature like "Virtual Folders" in LabVIEW projects.
Maybe also allow the addition of (titled) separators, similar as in favorite menus of web browsers...

I've seen "dummy sequences" soooo many times. Virtual folders (with ability to nest them) would be great. I think most (if not all) of TS user would give kudo to this idea, but unfortunately not all of them visit this part of the internet...
