Workspaces are a great feature. However, is there a way to sync workspace across multiple windows? I've seen some posts about this before but they have not been resolved?

Basically, I own two monitors. I have my Opera opened (we will call this Window 1). Sometimes, I will create a second opera window (Window 2) [Ctrl-N]. Herein lies the problem, workspaces in Window 2 are completely empty as is consider a whole new 'profile'. Some problem with this is that:

• When trying to switching between workspace in Window 2, they are all empty
• Closing Window 1 before Window 2 removes all the existing workspace tabs in Window 1 (the primary window) which makes it troublesome to reopen (yes I know about Ctrl-Shift-T)
• There is no fast way to move all the tabs opened in Window 2 back to the correct workspace in Window 1

Is there any solution to this?
