Hi,
The Ecosystem needs a lot of work to become a integrated solution, it's missing a lot of feature that will be expected if integrated.
I would go even further and say it should not be just integrated in PlayMaker, it should be integrated in Unity as a Module, so that it's always there! because the ecosystem has potential for far more than PlayMaker, I can serve any script, any package, any assets for Unity. I started new features that allow me to scan you project and check for what asset needs or can be updated, filter your search by assets etc etc. It has the potential to become an essential part of the production workflow for any project and provide a true platform for community sharing with the right tools for publishers and participants as well as consumers. It's not far off as is actually. the fact that everything is publicly available even without the ecosystem browser is something that would really complement the Unity Community good spirit.
Bye,
Jean
