you don't necessarily have to start by writing "Code..."
so it will be sufficient to create your text files (the snippets) in such a way that you can filter them, if they are all part of a single library.
I mean, for example, my string snippets will probably have names like: str_RemoveSpaces and by just typing "str_" I can more easily select what I want to insert.
