Personally, I like it. Usually I will have something playing, music or the like in another tab or will have multiple media tabs, so I will have a small PiP on the bottom right hand side, makes it easier to manipulate on the fly. Alternatively, I will just push the tab with the screen onto the sidebar, since this is what I did before this option became available.
On my laptop, I update my bashrc on Excel, in Wine, then export it as a PDF, OCR to .md, Pandoc it to an .Org, and then finally, write it down on paper and re-type it on my phone’s Termux’s Emacs instance, then TRAMP it to my PC, in the other room.
I use biebian, btw.
