I am still working on addon support, by adding more UI elements and event registration. You can take a look at the screenshot below to see how an addon could now replace the default UI. Moving forward, the default interface might also be converted into an addon. The great part is that part of this effort is common to the NPC scripting, which will come after the addons video.

Let me know if you have any questions or comments. Cheers!
