Where is the source code and bugtracker for WoR-Imager?

The WoR-Imager about box only mentions the GitHub repository for "Translations":

This is very misleading.

Where is the source code and bugtracker for WoR-Imager itself?

There seems to be

https://worproject.com/bugtracker/my_view_page.php

So is WoR-Imager not developed on GitHub, unlike the rest of the project?

This makes it really cumbersome to contribute.
I am not bothering to sign up to a single-project bugtracker just to report an issue.
Please consider moving this to GitHub in order to facilitate easier contributions from casual contributors. Thanks!
