I'm very happy to hear about this Opera gamer browser initiative. As soon as I knew it instantly came to me an idea that I think is very useful and a big differential. It would be an overlay called via a configurable keyboard shortcut that would allow the player to use the internet and features in Opera without minimizing the game screen
or leave full screen.
I believe it would be a very useful feature that I would use very often.
I would be very grateful if the development team considered such a posibility.
