Feature Request

The little hover info that is shown over procedures is helpful but it defaults to using the information from a module level interface rather than the implementation in a submodule. I have most of my documentation in my submodules so the hover info is much less helpful. Is there a way to change this?

This is purely handled from fortls the Language Server that parses your codebase, and currently there is no way to do this.
I would argue though that the API docs should live at the interface and not the implementation, only implementation-specific documentation should live in the submodule level.

I'll move this issue to the fortls repo
