Cascade 2.0/Niegra

With sequencer being completed and the development team focusing on cascade 2.0 I was wondering if we could get some basic information on it along with a WIP thread. This thread would not be intended to slow down development by requiring pages of descriptions I would be happy with a paragraph and screenshot every time a feature is completed(P.S if this makes a slowdown in speed or productivity don’t bother). The ability to suggest improvements while you are still working on that feature would make everyone happy.
The basic information I’m looking for would be. What’s the goal? Higher quality, better performance, faster development, or all of the above? Is it such an improvement that I should wait for it before I do a lot with particles(get all the other stuff done first then go crazy). Anyway cheers. P.S Is learning resources the right prefix?
