I have an idea for an IDE that stores functions independently, and instead of being contained in classes/modules defined by syntactical scope delineated by eg curly braces, they simply get tags that you can browse/search/filter in various ways. I image something like a UML class browser with little planes containing code snippets and connections between them for call graphs etc.
