We believe that the most effective way to manage a product like this is to ensure that there is minimum repetition of code. So before contributing a function, please make sure that such a feature or function does not exist else where. If it does, the try and extend that function to accommodate your use case.
DocTypes are easy to create but hard to maintain. If you find that there is a another DocType with a similar functionality, then please try and extend that functionality. For example, by adding a "type" field to classify the new type of record.
