These hot buttons are the default ones though twice the size. I kept the arrows tiny.
I upgraded to a 4k monitor that is 28" and I could barely see most of the UI. Going to rewrite most of it piece by piece then hopefully upload the entire set ~
Update 1.05 - Centered the spell icon which is still tiny without updating all the icons.
Update 1.1 - Reduced Outer Ring on Spell Icons so it was somewhat more appealing
