On OS X the behaviour for the Cmd-T hotkey is to open a new (non-private) tab regardless of the currently focused tab. This can be a little counter-intuitive at times as I often expect new-tab from a private tab to also be private (and forget to use the private-new-tab keybinding). This only seems to be an issue when the private and non-private tabs can share the same tab bar.
Is there any mechanism at the moment to use the currently focused tab to set the privacy of a new tab for a keybinding rather than having to remember to use a separate hotkey? If not it would be a useful feature!
