One thing I haven't figured out with container tabs: say I'm currently in one of the container tabs and I want cmd + T to open a new container tab. This doesn't work by default, AFAICT...instead it opens a regular non-container tab. How can I make it so that I get a new tab for the same container I'm currently on. Right now, I have to either go to File > new container tab or right-click the tab and click "new tab"..but I don't like using the mouse.
