+1 for workspaces / tab syncin accross devices.
Plus, while we’re at it, could it be possible to manage opened tabs from a device from another device as well?!
Let me give you my use case:
- I have a bit more than 400 tabs opened on my phone (yeah, I know…)
- I tend to read them on one of my pc, either Work or Home
- It would make my life So Much Easier (!!!) if I could close the phone tabs I read on my pc from my pc !
Because going through all my tabs on the phone and closing those I read on my pc is a bit annoying 
Also, cherry on the cake, could we have an option to filter out these tabs in the "Tabs"? Like by Most recent for example…
Because Opera IS the best browser there is but this tab management/synchronisation is a bit IE6-like for now
