A few things I would love to be able to see implemented regarding tabs.
Active window uses the same preference as when closing a tab when dragging a tab out to create a new window
Ability to drag and add a tab into an existing window
Ability to snap to certain size ie.1/2 or 1/4 of the screen when dragging a tab and creating a new window
basically like how the tabs behave in chrome.
cant wait to see what the future holds for brave as things are added
