I’ve been involved with the Flight framework since its inception at mediaRAIN. I’ve helped Tyler with it via brainstorming, feedback, etc. But he’s been the one mostly to code it up.
It’s been great from the beginning for a lot of our projects because it has built-in undo/redo and allows for some quite custom things along those lines. Well, Tyler went in another direction with it for awhile, wanting to please everyone, taking out Singletons and such for example, and mediaRAIN forked it into a project called Nimbus. I will probably be helping out with both as I can.
Flight is now coming in from the wings more with their changes and it looks like quite a solid and complete framework, even if I didn’t need undo/redo. I’ll have to try it out with Layered Content as I upgrade the admin.
