Something that would be very useful would be being able to change the zoom of the websites (like in Kiwi Browser). That would be very useful for when you use Brave on the tablet (or foldable phones) and we want to browse in desktop mode and need more space to work.
At least for me, it is annoying to activate the desktop version and not be able to see it smaller (and larger) like on the computer, since there are websites that have many menus and they do not display the same as on a real desktop.
