It's looking awesome Nao. I'm using FF13 and it seems pretty seamless.
I'm not sure if I should post this next tidbit here or in the bug section and I apologize if it's in the wrong place. I don't *think* it's a bug, just a loading time issue.
When clicking on the quick access drop-down menu and selecting a board / section, I receive a "Loading" pop-up message at the top of my screen. The loading hangs for about 3 seconds before I'm redirected to my requested page and this happens regardless of my destination choice.
In any case, I'm definitely loving what I'm seeing :).
