Zxian, you're 3 months late, in discovering those hover-previews & changed keyboard shortcuts All those features been present since the TPs itself! And as said above, the beta1 is slightly older than last weekly build, so is a bit unstable. Anyways, you can always re-map keyboard shortcuts, but it would be better to get used to the new, since all browsers now have standardised them (IE7,firefox,Opera9). New Tab - Ctrl+T Bookmark - Ctrl+D (i'm still not fully used to atleast those 2 shortcuts, for which i was using the old-style ones, i keep tripping up on them once in a while)
