Once I'm done with the rewrite of the gfx stack, the hourglass will be independant.
I can't (won't) change it for now though because the more changes I do to UI now the more annoying it is to backport to the new renderer.
But know this wont be forgotten (as i'ts already implemented there
What would also be nifty: being able to change the "direction" of one of those tabs, and being able to dock them to each other.
For example, I have my ressource bars on the lower right where I got some space to the left of the action bars. Above that I have the buff/debuff columns.
The problem with those two is, that if one of them gets very long, they start to overlap with each other and grow out of the lower border of the screen. If I could chose any direction for growth *and* link them to each other, that would solve all possible arrangement deficits.
Its nothing major, but since you seem to be doing some UI groundwork right now, it might be a good time to think about this functionality.
