But.... I've worked on this all night without sleep, so I'm not going to put it live. I'd be asleep for the first 12+ hours of bug reports. :-)
So, please test:

Try:
-- making styles
-- editing styles
-- using system colors
-- using your own colors
-- all views
-- all stupid S1 tricks
Everything should work exactly as before (except faster). Any deviation is a bug.
