Maybe a good start, and the obvious choice, is to keep the same FCPX categories like effects, titles, transitions etc?
For reasons that Alex has gone into, this wouldn't be the kind of organisation that would most help.
If you're looking for a "plug-in", "effect", "template", call it what you will, you're looking to solve a particular problem or find a particular design solution.
What you don't know is whether the solution that will work for you is an Effect, a Title or a Generator. Depending on the developer's thinking, it could be any one of these.
My feeling is that Alex's suggestion is the best so far - the categories make sense in terms of what you would go hunting for.
