With 2.5 out the door, I finally got some time to work on new features. I love that part - to me new features are so nice - the first couple of weeks always feels like you're the world's fastest coder (after that, reality sets in and you actually have to make it work in real life - even for corner cases).
Rune and I are busy on the new animation timeline. (Actually, I'm stealing his thunder - he's doing the real work while I'm just mocking up in Photoshop and spreading general confusion) We're basically going for a complete rewrite that gives you control over all curves with key editing, tangent dragging, the works. - have a look at what we're thinking:
I'm really excited about this. I'm thinking that it should be able to require a lot less scripting work for a bunch of stuff. It will also support material animation (so you can actually just make some curves for a UV scroll - instead of having to code the thing from scratch).
