I would like to request to have a horizontal actionbar

I dont know how to explain it. Because my Game Resolution is 3440x1440 (Ultrawide). The Vertical Actionbar on the right is hard to access.

So I would like to have an actionbar like this. This what my actionbar look like from my addon bartendender4+masque.

I think that the only thing missing in your kkthnxUI. Ability to Customizing Actionbar layout. So far im liking this UI

This has been added. Check actionbars section in latest github version.
