A separator for streams

Hello.

When there’re many streams, it becomes tough to manage them all as a list. It’d help very much, if there were a way to make a named separator to divide the streams. With tabs even better. I see it like this:

[tab 1 = Windows]
— [Separator 1 = Servers]
---- Stream 1
---- Stream 2
— [Separator 2 = workstations]
----- Stream 3
----- Stream 4

[tab 2 = Linux]
— [Separator 1 = Ubuntu]
…

[tab 3 = Network devices]
— [Separator 1 = Switches]
…

And etc. Maybe there’re some plans for something like that?

Thanks.
