Could you add the two options?

Could you please add the two options? Thanks you.

  1. For locked Tab, make it impossible to be closed unless it is unlocked.

  2. For a directory which has been opened in a Tab already, if user try opening the same directory again, switch to the existed Tab instead of opening a new Tab.

  1. Is already possible in some situations. You can use the "Go NEWTAB=findexisting" command.
