I'd actually even make all the zone options available for every single zone. Many of these have overlapping usefulness. Agriculture ought to function with zones too instead of "built" plots.
You mean like you can do now?
Rooms could also be based on zones. It would be a lot less anonoying to have beds auto moved to zones than having to place each one separately. Especially if you could combo dining/throne/bed into one apartment space.
Or, with a little more detail, room templates, kinda like a combination of burrows and zones. Designate a new template of 'basic bedroom', for example, with 1 bed (any type), 1 coffer (any type), 1 cabinet (any type). Or a 'noble bedroom', wich 1 bed (masterpiece), 2 coffers (masterpiece, obsidian), 2 cabinets (masterpiece, obsidian). Etc. etc.
Then, just plop where needed. Of course, the dwarves will put the furniture in ugly locations, but oh well.
Maybe set up zones where dwarves can pay rent and buy and install their own furniture?
