I’d love to have Brave show tabs when you mouse up to the top of the screen when in full screen mode. Full screen is a significantly better user experience when you’re not having to flick regularly between tabs, but it’s a frustrating compromise to have to F11 out of it or use keyboard shortcuts to page through the tabs - or remember which order your tabs are in so you can shortcut directly to it.
Edge has a really good mouseover system for switching tabs in full screen and I’d love to see the same thing in Brave.
