Hi,
This would be great, but not really practical for many reasons:
1: *ALL* scripts are recompiled everytime there is a change, so the more scripts the longer Unity will take to recompile, build, etc etc, so keeping a projec to its bear essential is highly recommanded, even when not using PlayMaker.
2: Unity is moving away from including everything, Unity 5 uses Modules, which soon will likely become optionnal so that someone not using physics can remove it all together and no be bother about the time it takes to deal with that aspect.
3: some actions are platform dependant, and de facto, not every action make sense to have, or would throw errors.
4: depending on the projects, some actions will never be used, why polluting the actions browser with a huge list with mayn actions totally not needed.
So, yes it's more effort, but that's why I am trying to solve with the
Ecosystem, so that getting actions is just as easy as browsing existing actions with the Playmaker Actions browser.
There are plans for the ecosystem to offer a way to favorite actions and in one click indeed download all your favorite. But you can do this already yourself very easily. select all actions you like to have, make a package out of it, and keep that package in a spot you can quickly access in your os, and then when you create a new project, simply get that in there as well.
Bye,
Jean
