9.1 was a maintenance release, so this was to primarily fix bugs within 9.0. There was of course the new data feed that was added to the MetaStock Professional lineup, QuoteCenter. I do have a list of the fixes if you really want, but most of them are uninteresting, installation issue fixes, a couple minor system tester fixes, etc.
No, they keep saying they will implement it but the original programmers have left Equis and I don't think they have a clue what they are doing there now, every release has been bells and whistles but no meat, they are rehashing the same program with a pretty new box
