• Do you think the diff size would be useful to have?
• The page has not been optimised a lot for mobile devices. Perhaps that is less required... on my notebook screen, it certainly works well enough if I shrink the window.
• If horizontal screen estate is an issue, the "updated" column could be reduced to "3 hours ago" or "a day ago" without much loss of information.

• Diff size is implemented in 49db1d8a2834ac2653f797812356644ac208d243 and 6ae77b2b427b57752217c388defc58eafb79b417.
• Mobile responsive optimization is not a prio for me, and I'm not particularly skilled in doing that. PR's welcome though.
• I agree that "3 hours ago" should be enough, but we loose the ability to sort, I guess. So I want to store the date somewhere where it can be shown upon hover, and such that a sorting function can use it as key. But I haven't figured out how to implement that yet.
