Definitely agree with the first two. I think these are important.
For stuff like wild magic rage, I intentionally leave a slot open on the wheel for where I want it to go. This only works if you fully fill all the wheels from right to left. It's a little bit of a problem if you only want to put a few skills on a wheel towards the right of the list.
I think the biggest problem with the way the default selected wheel works is that it's always the left most wheel, which is also the side that new wheels are added on. If it defaulted to the right most wheel it wouldn't be an issue. (Besides arrows etc)
All great ideas!
