Conditional Formatting is a whole lot better, IMO. I think I can use FMP12 now.
Desktop is not quite FM7 render speeds in a complex layout (converted db), but close enough - a fair trade for all the new UI goodness. (imagine be better with native FM12 layouts too).
Complex Form layouts feel much more responsive. List & Table scrolling is way better.
Thanks FM Inc engineers, was getting little worried might have to live with it for moment there.
Can start shouting about 12 now.
