I like it, at least as a start. I had some macros and so forth to do something similar, but I'm happy to clean that out as I never was fond of maintaining it. I have a tab for combat job switching, one for doh/dol, one for utilities, and one for my most used crafting macros.

On my wishlist of changes we'll never see: Make smaller or, better yet, resizeable. Make changing the tab icons less janky, holy moly! And, make each tab have its own open/close option. Like, job switching tab I want to auto close, but crafting macro tab I do not. And yeah, I realize that's on me for treating it like a hot bar.
