Mockup http://cl.ly/image/2v3L1C3U3z34 As part of our tab tray refinements, let's bring the tab tray up to the top when browsing in portrait mode. It's a more efficient use of UI space, and is more useful and looks nicer than a giant empty sidebar :) * Tabs scroll horizontally in this view * Synced tabs scroll horizontally in columns http://cl.ly/image/2l1T2C3G2I0s * Swipe up to delete normal and private tabs

(In reply to Ian Barlow (:ibarlow) from comment #0) > * Swipe up to delete normal and private tabs Swiping up to close in portrait, but swiping left/right to close in landscape seems a bit confusing. And is opposite of what happens in bug 817735.

It's opposite because we have different UI structures for tablets and phones. Phones are too small to present a useful sidebar for tabs, and tablets are too big to have the tab interface take over 75% of the screen when it opens. As for the different scroll / swipe to close orientations, I'll paste what I noted in bug 817735, that it's a pretty common interaction on Android ICS+ nowadays. Take a look at Stock Browser, Chrome, the App Switcher. They all use a similar model and it's fairly easy to pick up on. If it is too much for people to handle, we can add in a more visual affordance, like a close button, if need be.

I'll be working on this from now on. I'll start with the horizontal listview/gridview changes in tabs tray.
