As I see it there are two related but different issues here.
1). Be able to navigate from an external module to other files. Other external modules already works thanks to default_external_modules preference. Should also be possible to navigate to records and macros, which means some kind of global include must exist.
2). Be able to code complete module and function names in a non-external module based on external modules defintion. Should be farily easy to do without having to fix 1), given that we can already navigate to these? I create a separate ticket for this.
