> where we are now (tabs on top, no wasted space) Tabs at the top is wasted space, I much prefer my tabs on the side instead, as most web content is taller than it is wide, and I have a widescreen monitor. I understand the choice of tabs on top when 640x480 was the most common resolution, but for desktop usage today? Tabs on top seems like an outdated layout choice.
There are browser - Vivaldi for example - that allow you to place the tab strip on any edge you want. To me personally it just looks and feels wrong, maybe just because of years of exposure to tabs on the top, but I can not get used to it, even though I have to admit that the tab labels are much nicer to read on the left if you have sufficiently many tabs open.
Side note: it infuriates me that Microsoft’s web-Office will “helpfully” remind me that it auto saves when I do Cmd+s but also captures the event so that Arc can’t handle it. Which reminds me…I can probably whip up a quick Boost to get rid of that - yay rubber ducking in the comments!
