Hello everybody,
In Fact I had to use an alternate tricky option to sync my opened  tabs per workspace as you wish. So, how and why did I land on this topic? simply because I was searching like you all for a logical way to do this synchronizing without hassle!
The solution is:Recently after opera added the pinboard feature you'll be able to share your tabs easily to anyone... So why don't use this feature locally with yourself and convert it from "Share" to "Export"!!How? go to the pinboard page and create a new pinboard and name it as you like.. for example name as "For Export" or name it as your workspace name exactly... then head to  your existing workspace and pinboard every single tab to the created one which is "For Export''.After you finish copy the link of the pinboard or sharing it with yourself via Messenger, email draft, Clipboard whatever and open it in your other device Opera browser... you find inside it all the grouped tabs that you want and then add them to the local workspace on that device!.
I know it is a little bit long solution, especially when you have more than 10 tabs opened together! but at least it works 100% and

what is the proof that this extension creator or the company behind its developing can't see or spy on my saved passwords list?
does it saves them internally?
No, so give me a reason to trust an extension that saves my important password online and anyone can hack my account and still them or even the same software programmer can spy on them!
