It would be nice if the different sub-modules were grouped when using addons like Addon Control Panel. This can be done by simply adding the line:

## X-Part-Of: CTMod

to the toc manifest file of each module. (Or whatever other name you want to have be the main heading)

If I understand right, what you mean is that ACP will look for a custom property titled "Part Of" (X-Part-Of) and use it to conveniently group stuff together?

I am certainly happy to do this.
