I'm moving the topic from "the marketplace" to "Gantry 5".
I'm afraid it's not practical to do that and in any case may not give your what you think. Each of the commercial templates comes with some particles. Even those these particles may be called the same thing as other templates they may, in fact, have very different functionality. So an "owlcarousel" particle in one template will have different functionality to other templates "owlcarousel" particle.
What we do in the template demos and rocketlauncher is include a page under "features > particles" that shows any new template specific particles included with that template. Of course, on top of that, there are the core particles that are included with Gantry 5 itself.
Regards, Mark.
