I would like to use the function signatures mainly for autocompletion of the 'namevalue' argument options in the Command Window. My problem is that I tried to define the function signatures of a function that is in a subpackage and I get the message "Cannot diplay function hint. Cannot parse more than two levels of dot referencing". Heres an expamle of the structure of the package.
How or where should I define the functionSignatures.json file to be able to have the functionality I seek?
UPDATE: The autocompletion works as intended for namevalue arguments, it's just the function hint that isn't displayed that I'd like to know how to fix.
