I wonder if this-view-but-for-browser-tabs would be useful.
E.g. instead of opening 4 google search links as tabs, you could just open one "to the side" and quickly go to the next link if it turns out to be SEO spam (and avoid a click to close-tab or back-buton).
I've thought of this too, along with the possibility of having multiple tabs visible in the same window generally (almost like a screen/tmux/byobu/… for a browser with tabs being panes in tmux's terminology⁰, tabs->windows and a browser window being a session).
That is probably a very niche desire though, so I don't hold hope of seeing it implemented/supported and don't have time to try write it myself.
This is not built in, but fyi I've used PaperWM for this (scrolling tiling window manager on Linux) and open new tabs as windows. New windows open to right in a large scrolling desktop basically.
I've found that I'm using this feature much more than I thought I would in arc. Before, I'd figure that it's the same as opening two windows side by side. It's not, having it as a built in feature opens up a lot of things. Opening an article on HN and the comments on HN side by side, for example. I NEVER did that before, now it's second nature.
I think this style of browsing really shows its strength for research and review type tasks. Maybe I'll research what it would take to write an extension to implement some of these ideas.
I was trying out Arc and almost forgot about it, but now knowing about this feature changes everything, thanks for pointing it out! Very often I need to see two or more pages side by side and I just hate making a mess in my browser with multiple windows open. They just tend to get lost and I have to move them out of the way or close them one by one, it is just annoying.
You can even have more than two splits, which I did not expect. Also, holding the option/alt key when clicking on a link opens it in a new split which is super convenient.
Vivaldi has this functionality as well, although the UI around it isn't great. There's no easy way to swap one pane with a different site - you have to untile the existing sites and retile the ones you want.
YES! I've wanted EXACTLY this in my browser and IDE for some time. I'll do a little research every once in a while to see what it takes, but never get very far. I really like iterm's keyboard shortcuts for new panes (vertical and horizontal split) and tabs. I think it would be such nice ux for browsing web and browsing code.
Also with the ability to fullscreen the active pane quickly. It's SO nice.
