If there is one thing that will make me swap back to another browser again, then it is the problem that if I am pulling a tab out of the current window it swaps to the GX Corner instead of the actual tab that I just pulled out.
This is quite the annoyance if you pull out the tab quite frequently, because of a multi-monitor setup, and have to additionally swap the tab every time as well.
While I love the GX Corner itself, I think forcing it in this way upon others and me will just be an inconvenience, which will not be healthy in the long run.

Hope you can act upon my feedback and keep bringing us great updates! Many thanks!
