Hotbar Customization Suggestion

I'd like to make a suggestion to sort of 'borrow' a feature from the Gamepad setup for the Keyboard/Mouse setup- hotbar customization switching for weapons drawn/sheathed.

At first I thought I had been overlooking this, considering how useful it would've been for reducing screen clutter in combat. Evidently though (or as far as I can tell, rather), it seems to be a cross-hotbar only function. Could this be applied to the keyboard setup as well, to hide selected hotbars while our weapons are drawn?
(Or if I'm overlooking another way to do this, can someone elaborate?)

Heya

I use a simple macro to hide specific hotbars. I use 5 hotbars for battle and all the others for stuff e.g. mounts, pets, quick acess for menus ect.

/hotbar display (number of the hotbar)

If you write this in a macro and use it, then your hotbar will hide or shown.

I use

/hotbar display 6
/hotbar display 7
and so on in a single macro to hide this hotbars to reduce clutter in fight.

An option to hide it automatic at specific situations... uhm i don't think this exist.

I hope this helps a little.
