Currently, it is not very convenient to share tabs across devices. I have to go to the menu and then view history to get my tabs opened in other device. This could be made a little easy by moving the Devices as a whole beside brave wallet or just add an icon for each device synced, thereās plenty of room there 
Same goes for the android counterpart, sharing tabs is pretty difficult, go to shareā¦ devicesā¦ then send it to one. It could just be added to the vertical ellipses.
Thanks for the awesome browser though
