Thanks. Now put one of those spell icons into the hotbar instead of that generic Air element magic one, arrange the icons above so the level one are closest to the hotbar, level two spells above them, level three spells above those and so on.

Make each line as long as necessary - horizontally. There doesnt need to be any space left for other types of spells since one element would replace the other.

That should be it.

Of course, you dont have to actually do it, this is just a description.
I didnt have time to make something like it.

maybe ill try something tomorrow.
