I have always loved Snippets and the whole Chrome Souces ecosystem in general. In fact, I use Sources as my editor of choice over Sublime, Notepad++, etc. I find the "map to local" feature outdoes anything I use from the other editors. Only gripe is I wish snippets were stored as text files (or at least that was an option)... couple weeks ago my Chrome profile got corrupted and I lost like a year of snippets.
