I am new to ErpNext and have gone through the tutorial. I see how you can create new models modify them, etc… Im loving the completely responsive web desing. What I have not seen is if you can modify existing views from a module and how. For example, as a way to familiarize myself with ErpNext I want to create a module that expands the functionality of the Point of Sale, but I am not sure if its possible to create modifications over the PoS template and js code from a different module and how.
Also, can you create models (DocType’s) programatically in python instead of having to use the GUI?
