Question like this can be posted on the forum, and I'll flag it as "Development" to bring more attention from other devs besides radfast and micdoodle.
In advance, I recommend checking out our addon API tutorials (https://wiki.micdoodle8.com/wiki/Category:API) so you can get some grasp of how we develop addons and how the main code handle it.
Thanks for the answer. Where on the forum should I post it? There is no category quite appropriate for this. Next, the API tutorials are incomplete and seem to be outdated. The Github repository is probably more useful at this moment.
