As I just started using the sync feature I cannot find vital functions that would make it relly usable for me. These are:

The tabs synced from my phone have to be opened in tabs in Opera. As I really like the workspace-feature I think it might be great having a dedicated workspace which automatically opens all the tabs opened on my phone.

Furthermore I'd like to see the feature to close tabs opened on my phone from my computer - like just exiting a tab in the proposed workspace. As of now I would open a tab on my pc, read through the information and close it, but I would also have to find the same tab on my phone and close it there. This is not really convenient and takes too long so my phone's tabs stay cluttered.
To me, it would suffice if this was possible via PC and I do not really need being able to delete tabs opened on my pc from my smartphone, but it would also be nice to have.

These would greatly improve usability and productivity as it would eliminate the need for manually closing tabs on my phone after having opened, read and closed them on my pc and by being able to sort through them via my pc much faster.
