Is it possible to group multiple instances of the same “Brave Browser App” into a tabbed window without going full browser?
More Tools → Create Shortcut → “Name” 
Open as Window
I know it seems counter intuitive but for the purpose of automating daily application launch and multiscreen layouts, the brave app windows work well. However, I need at least two tabs of the same web app open to cross reference/context switch a bajillion times a day.
I think I know the answer will be, no there is no way to have tabs of the same brave app within a windowed application instance, but just thought I’d ask…
