Feedback sent. Looks like it could be interesting.
A lot of the mentioned features were stuff I hadn't thought about. I probably wouldn't be all that into them, but I can see other people liking them.
I'd have checked the "yes I'll beta test if you'd like" but technology often hates me. My wife is in the computer industry, and when I complain about something having gone wrong like IE crashing(not for some time now I use the new browser) she asks what I did and the answer was usually "I clicked on a link"
