Not today. The GUI offers everything which is currently supported and 
the documentation is up to date, too.

Yes and no... it all depends on what a specific user wants to achieve, 
and so far the filtering by class wasn't requested by users.

It does make sense to add it. Don't know when we can squeeze it in, 
because it's an unknown amount of work and needs making changes on each 
and every supported platform, plus adjusting the API, GUI and so on.
