It is a conversational tool that can generate decent code if properly prompted but it lacks for the most part enough context. For it to be really useful it has to be able to be trained on my entire project that I'm working with, not just a single file or function.
What I miss is the ability to "chat with my project". I.e. have the whole project in the trained context, and then reason about architectural changes, pros and cons, have suggestions for refactoring, help with complex renaming schemes and moving code, etc.
It would be super interesting to be able to give instructions like:
Organise my files by dependency and the logic they implement.
Or something like, create web components from common input elements in my html pages.
