No easy way to close lots of tabs

[fffergal]

When I want a new tab I just make one and don't think about the tabs I have already. I like to occasionally go through all my tabs and close the ones I'm not using any more. Closing lots of tabs on Endless is hard as you can only see the contents of one tab at once, and the target for closing a tab is quite small. After you close one tab, the next tab is opened and you have to go back the tab menu to close more. When I'm not wearing my glasses or my wrists are tired hitting the small x is even harder. Safari shows a peak of many tabs at once, and uses a broad swipe to close tabs.
