I can't drop this.. not that I don't agree, more how it would work :)

So one workspace has control of the attached screens.
workspace 2 has that to and there for can have another type of duel
screens or perhaps only one active.. right?

So the best place to storage information about screen combination would be
the workspace?

Reason that I'm asking are that I have just reading about BScreen and the
app that configures Nvidia cards uses BScreen flags to do that..

But BScreen are only one screen and not only that in the future it can be
a TV? But we/ I will concentrate on duel screen thing, who / where can
such thing like duel screen settings be stored?
