That's great news! Looking forward to being able to use Makinom schemas instead of Events.
My top request for ORK 3 was a database structure that is more accommodating to multiple developers and source control systems, and it looks like you've got a good plan for that.
A close second would be a GUI system that is designed specifically for UGUI, which would essentially be a set of specialized databinding components that would be attached to GUI objects so that it could be designed visually. Legacy GUI had to be created programmatically, so ORK's GUI system was a nice extension of that. However, it feels very limiting compared to working with UGUI natively, and it's also very time-consuming to set up due to having to run the game, look at the menu screen, stop and change values in the ORK editor, run the game again, repeat...
So any chance of a more visually oriented GUI implementation? ;-)
