I've folded the specialist stacker and specialist buttons from the file on the first post into BUG. There was an bug in that the specialist banner did not get deleted after the city become large that I had to fix - not a biggie.
I also added another specialist option (Chevron) to BUG where some specialist icons get a chevron to show that they represent 5 specialists, a double chevron to show that they represent 10 specialists and a capped double chevron to show that they represent 20 specialists.
That way, I can show 25 specialists by two icons: one with a capped double chevron (20) and another with a chevron (5).
