Comment 18 for bug 1680891

The simplest thing to do is to call the save function whenever you make a change (add/edit/del). This would update Terminators internal state, and the menu should be immediately updated. It's not particularly elegant, but it should work. The disadvantage is that the Cancel button stops having an effect. Better would be to add an Apply button to the OK/Cancel area that calls the save function.

Of course the window is created as a modal window meaning that the launching instance of Terminator cannot be used until the configuration window is closed. Fixing that may be as simple as removing the modal flag at window creation time.

Also be aware that if you are running Terminator without DBus, then other instances of Terminator will not see the changes until they are restarted.
