The Control+Shift+F shortcut is not working on OSX. Cmd+Shift+F is default system shortcut for full-screen.
Please allow customization of shortcut. I understand you want to minimize configuration, but this is very individual setting.
It would be *awesome* if we could drag-n-drop tabs from one container to another (that would reopen the same URL, possibly with history, in the target container while closing the tab in the source container) or between the windows..

Lots of potential in this extension.
