If I understand you spell suggestion the problem you describe is that we can't assign "direct cast" spell icon of a "native spell". So when we assign level 1 spell to hotbar, it will always be the version that will require confirmation (same with other level once upcasted version of them is available).
Yup ...
That is the problem.
That's not something I discussed
But in fact it goes even one step futher.
And that is what you were talking about ...
Since the game is curently unable to asign "direct cast" for lowest possible spell level ... when you filter your spells to show only level 1 you would presume the game offers you "direct cast" icons ... instead you get those "native" that require confrimation.
So my suggestion would solve two problems at once.
Game would start to understand direct cast for lowest spell levels ... so level 1 filter would work properly ...
And people like myslef would finaly get the option to cast Mage Armor level 1 with just single click instead permanently confriming its level.
I see it as win win situation.
