The current way spells are, if you want to be able to cast cure wounds at level 1, you need it on the hot bar. It you want to cast cure wounds at level 2, you need a separate spell, cure wounds level 2, on your hotbar. This is going to make for a mess of hotbars. I think just having the spell, then a small pop-up option to pick its spell level would improve this and prevent having the same spell for every level. Hope this makes sense.
I agree, that should be the way to go.
