Last night (well, in the wee hours of this morning, really) we released the JavaScript/Ajax wonder I've been working on for a while, and I'm too excited to not blab about it just a bit.
The relevant bit is (what starts) as the bar across the top (of CCHits in this case), and all the stuff inside it. Basically, we got rid of the sidebar, and removed the need to hit the system pages for most things. Oh yeah, it is wholly rebrandable, and you can get rid of it if you don't like it (I bet you will like it, though)! Nice and all, but more fun is how programmable it is -- the whole thing is designed to be fully customized by app developers who want to change what we think is useful into what is really useful for them. Aside from the JS, we added web services to do access the majority of system functionality without having to hit our system pages at all!
As with the content store, most of the core functionality is exposed via APIs, in this case most of the new ones use JSON instead of Atom as the most common client is JavaScript in the browser, and it is darned tooting nice to work with. I'm going to shut up now and go pack for a my trip to Italy. Poke at the docs if you like, please (I didn't write them, but I am extremely excited about it all).
Update
Gina is awake enough to done a much better excited post. Check it for more details.
