It works, I like this feature and I am thankful even though I can imagine it to be even more comfortable. I like to plant the idea of making it a case-specific decision. From other plugins I know the implementation of different buttons on the bottom of the editor, something like Save and Save and return to overview or the other way round Save and Save and keep editor open. Or a save button with an additional check box to distinguish the following action.
Or in case of keeping it like it is right now, at least a button on the bottom of the editor to easily return to the corresponding overview would be handy. Like For the case where you edit several times the same template till you got it straight and then want to go the another template.
