I really like the concept, and I want to use it in full-screen mode (to make it feel more like a first-level OS experience even if it isn't), but sadly once you open a website in full-screen, the rest of the browser chrome goes away. Of course there are times when I'd want it that way, but there should probably be a separate option for full-screen with the browser chrome.
I know this is basically just an early prototype, so I can't really be critical. If anything, it's just such an effective and impressive prototype that I already want to adopt it for daily use :)
So this is my problem too but somehow I've managed to do it.
I've went into the Mission Control state and dragged the Neon app into a new screen. It was a pleasant full-screen experience with only the app full-screen and not an individual tab, which is what I expect from the full-screen mode.
Problem is when I tried it again, it didn't work. Not sure what's wrong but this is a newly released software so I'm sure they'll fix it.
Apart from that, it's really amazing. I especially LOVED the media control features.
edit: Got it now. Go into the full-screen mode when there no active tabs. Works perfectly after that.
