[Suggestion]Don't keep tabs islands when Opera is reopened

Hi there

I like the way Opera moved to the One version, there are some really good ideas. The tab islands are one of them but when I close the app and reopen it, all the closed islands are reopened and it's a bit frustrating to spend time closing everything again.
What's more, it could be very interesting to offer the Chrome feature that lets you rename groups of tabs.

Keep going the good work
