Addon Loader?
And then adding into each of the class-specific addons toc (
Wiki Page):
## LoadManagers: AddonLoader
## X-LoadOn-Class: Rogue
I'm using this system in all of my addons for speeding up loading screen by loading on demand / delayed.
On topic: If you move addons into a single addon, you'd need to take care of the paths from the textures / fonts provided by the addon, if any.
