twingeofregret As you can do in a number of other browsers, it would be great to close a tab by swiping left on its thumbnail in the gallery view.
twingeofregret Sorry, meant to file this under mobile (although this could be useful on desktop as well)
michael @twingeofregret please attach a screenshot of the gallery view that is reference here. You should already be able to swipe left/right tabs in grid view (if that is the case) yet we're about to polish this a little bit more for better UX soon.
