Not to diminish the effort, but the use case for this can only be a role that requires a ton of snippet handling, which inherently means you are doing something wrong as a programmer (imho). Once you get to a point where you are regularly using snippets a lot, writing some automated script is the next step, not a tool that makes it easier to copy/paste.
My use case for snippets is mainly to stub out tests, components, and stories - things that are largely an exercise in boilerplate code with fill-in-the-blanks changes to start with. I can't think of a way to do that with a script that would be less effort than a snippet.
