Just a very simple suggestion that might be easy to implement and probably useful to many people: When adding a new dialog option in the dialog editor, it shouldn't be added at the bottom of the list, but either at the top of the list or at the penultimate position.
Why do I suggest that? Well, when working with dialogs, you will be adding or removing options sometimes, but the last option will (for almost all conventional adventure games) always stay the "Goodbye" option. When you're adding things after it, it will move up and not be the last option anymore, and then you have to copy and paste all the stuff.
Of course, there is a workaround for that (just adding a dozen empty options and making the "Goodbye" the, say, 14th one), but it would be more elegant that way. And what would be even more elegant: Drag and Drop dialog options. But that's probably too much to ask.
