We had that already. Opera was the first browser with tabs, it had MDI support and tabs. MDI stands for Multiple Document Interface, and was common with Win 3x and Win9x (WinAPI) applications: https://en.m.wikipedia.org/wiki/Multiple_document_interface https://en.m.wikipedia.org/wiki/Multiple_document_interface . Macromedia Dreamweaver had tabs even before Opera browser, as well as Frontpage. Word, Excel and PowerPoint used to be MDI applications up to Office 2010 (up to 2003 with a good UI, kind of hidden but still that way until 2010). Photoshop on Win, older Acrobat, mIRC, etc use MDI and have tabs as well. Win3x had all the auto arrange and different MDI modes, Win95 unfortunately broke the "icon" MDI mode, though the mode still exists but doesn't work in Win95 or later. So it would be great if Chrome and other browsers would support MDI with tabs like the old Opera 4-6. Use could auto-arrange two tab-windows within the browser main window side by side or arrange them in any way you wanted by hand. Very unfortunately Microsoft lost all their proper devs from last century and with it all the previous inbuilt WinAPI knowledge - otherwise Win8 and Win10 trainwrecks would never have happened.
