Hi,
I used the data from RareCoordinator to create a module for the Timeless Isle: https://github.com/Urtgard/RareTrackerTimelessIsle
Do you want to maintain and publish this yourself?

Looks good! I would prefer to maintain and publish the module myself, with your permission of course. That way, I can have it be automatically included within the RareTracker addon.

Good. I started a repository transfer.
