@btcbtc How are you trying to connect the phones? You need to go to menu > settings > synchronization and backup > Connect Device in one phone and, in the other, you go to www.opera.com/connect. Then you se the first phone to scan the QR code that will show up in the second one. If everything is fine, you will see the same number on both devices and will click on the button that says that the numbers match.
@angelo2008 you are right !
It would be nice to move and reorder tabs.
Opera should also add space feature as desktop version. It should be implemented as "normal" and "private" menu in the "show all tabs" screen.
I hope that one day these features would be in their raodmap !
