Hi,
yes, I have this idea in mind too. What I would do while this is pending is remove all actions you don't want, then package them and put them in your Editor standard package folder so that it's here conveniently.
I also though about a tool that remove all actions like a totally clean PlayMaker install. then you bring only what you really need from the ecosystem.
The above would make sense only when the Ecosystem will allow login users so that we can create favorites list online and so when you login, you have some pre made packages stored on the ecosystem featuring only what you want.
It's a long way, but I hope one day I'll have the time to do this. My domain is already ssl compliant, so I'll soon be able to log users, that's the first step.
Bye,
Jean
