Allow smartcast with indicator on certain skills. Please.

Sometimes i just want a single skill to have an indicator, and the rest to just come out when i press it. For example, Veigar : I want E to have an indicator, but i can't afford to have everything else activate on key-up. Or Anivia's wall. I want the wall to have an indicator, but i want everything else on smart cast.

This will make all champions smoother, as some skills are just better off without indicators, and some aren't.
