Split tabs are now in:
right click a link, open in split view
Just for the record.

> 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
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...
no windowmanager anywhere supports that. even tabs could have been solved by window managers. but then we could not get inactive tabs, and the same is true for the tabs in splitview.
if lack of support for inactive tabs are no issue and if you don't use workspaces much, you could use those as a workaround. but that unfortunately at least gnome workspaces are not flexible enough for that. (i'd need dynamic creation of workspaces without automatic destruction, and i'd need gnome to remember which window goes into which workstation. that used to be a feature on some windowmanagers, but i haven't found any that can distinguish multiple windows from the same app.)
