It's alot more possible now. The main reason I didn't allow for that was my own ignorance at using XML files from .NET. However a recent project unlocked all that knowledge for me, so it's much easier now to add features that are saved and modified.
At the moment, I'm just waiting to see what happens to EUO. I haven't felt like supporting a tool for a project that was going to be abandoned. Once I get a clear indication that things are OK with EUO, I'll probably dust this puppy off again.
BTW, there is a way to force SUO to save your color selections. I just need to remember how to do that.....
