Yep, I'd also like to see them put in hotkeys
Push 1 and you get the first row, then hit a second number to cast a spell, or
They could do something like push 1, first 5 items highlight, push 1-5, cast spell. Push 2, second 5 items highlight, push 1-5, cast spells - would let you use only 1-5 to cast any spell or ability on the long ribbon right now. You could even add a third press confirm, with the second press popping up tooltips, so you know what you're casting.
