Suggestion: Stances and Hotbar Swapping

With the addition of new abilities in Heavensward, some jobs (particularly pet jobs) are starting to hurt for space on action bars/cross-hotbars. One thing that would probably alleviate some of this would be having an automatic hotbar swap for particular stances (like Cleric Stance) and also based on summoned pets. It wouldn't completely alleviate the issue, but it would provide some relief for SCH and SMN especially. Tanks also would benefit, since they stance dance quite a bit, as would BRD and MCH, since they have skills only usable while under Gauss Barrel and Minuet.

.. This is actually to some extent achievable with macros. You can switch your active hotbar to some other through macro, so especially for static use, like pet summoning, you can make a macro which summons the pet and switches your hotbar to the one where you have the pet skills OR sets certain slots in your current hotbar to contain that pet's desired skills. The latter is even better in some sense (if you don't have to make over the whole bar) as it doesn't require many additional hotbars to be saved.

edit: To clarify, I mean commands /hotbar and /crosshotbar and everything they can do through their convoluted subcommands options :)
