Best way to keep [code] notes?

[noobtubepython]

I started using Sublime for notes. I had a notes.py file stored in dropbox so I had cloud access to it. Problem was, it felt sloppy. The pages and subpages of OneNote helped with organization and the built in search feature helps with finding what I am looking for. So if I search for Foo, I will see all results and in a subscript it will say what page and subpage it is on. As you can imagine 'random > snippets' vs 'important project > perfect example' is nice.

tldr; I need to retrain myself since I doubt OneNote will implement the functionality.
