Some aggregation for Layer states and Model/Layout tabs?

Hi All.

Not sure if it’s already discussed.
Could it be handy to have let’s say a possibility to create a second row of tabs, like grouping tabs.
Which could also be associated with Layer states.
As an example:
Automotive designers could have “Front”, “Rear”, etc.
Interior designers could have that top level tabs with “Living room”, “Kitchen”, etc.
And switching to Kitchen Tab will switch all irrelevant layers off. It will only show everything related to kitchen.
There should be regular Model view tabs (Top, Right) under those Top-leveled.
Under those top-level tabs could also be Layouts of related drawings.
And it definitely should be a general top-tab, like “All”, where all layers and layouts are On.

What do you think?
