Didn't it used to be branded as lightweight?

> I fondly remember the good old days of 2004 when I first started using Firefox as my main browser and thinking how fresh and lightweight it felt compared to the atrocity that was IE. Firefox, sadly, got bloated over the years. So far, Chrome hasn’t put on the same weight

i occasionally need to compare two tabs. previously that meant that i had to open those two tabs in separate windows and then use window tiling to place them side by side. setting that up was a lot of work. and also it makes switching windows very hard. each side by side view would add two more windows that all need to be cycled through when i switch windows. and don't try to have more than two of those on a workspace. you'll go crazy switching between them.

with the split view it not only becomes very easy, but the split tabs also keep their position among all the other tabs, so i can keep the view permanently without cluttering up my list of windows. currently i have 5 split views in active use. that number is likely to grow...

I think it’s a nice feature. I use it to have designs on one part of the screen and implementation on the other. That way I can jump between “designs | implementation” and “PR | swagger” without managing and resizing tabs. Previously I had to jump between tabs and taking into account the newer screens provide a considerable amount of UI real estate there was screen area to utilize.
