Green means - it is good to recast dots now and red means - it would be bad to recast now.
But intuitively, I react to the colors the other way around. Green signals - all is good keep draining and red signals - something is wrong with the dots, do something!
I have a question, how hard would it be to do the same code for focus target? It should be possible to have two of these affdot windows floating around, right?
