Discussion - Set Aside Tabs and Warn on Close

please make it possible to customize the maximally frameless interface of Chromium, the ability to place (address string - URL address) and the tab string with control elements on the side or on the sides (customize each string separately) so that it does not interfere with reading text and viewing vertical video streams, etc. on wide-format monitors (so as not to switch to full-screen mode constantly with a large number of tabs) (if possible, make the interface as frameless as possible above and below) or at least implement this function in a similar way to - automatically hide as a startup in Windows) this is also relevant for Android devices and the function to remove the black bar around the camera - (status line, clock, charge, etc.) and
