Woo! I've been waiting for this!
To be honest, when you first released the beta (or I guess alpha?), I didn't really like it. But now you have sorted out the bugs and the lag, it's a lot smoother, and I definitely prefer it to the old editor. It's a lot smoother, and a lot easier to code. AND COPY AND PASTE, MODULO, AND ROUND ARE THE BEST THINGS EVER! I'm so glad you added them!
One thing, you don't seem to be able to drag math operators and values from block to block, which can get annoying. But that's not a big thing.
All in all, great update. i r8 8/8.
