Sorry, I thought this would be self explanatory. The editor in the sample browser doesn't really help, since only one document can be loaded and you can't configure the search paths there.
Basically to use a function from another Python module, you have to import it first. For example:
import package.module
def MyFunction():
package.module.function()
If the import statement is missing, the function cannot be used and a runtime error occurs. So it would be better to not show it in the intelli, unless there is a coressponing import statement. Currently the intelli shows them always, since they can be used.
To be clear, I don't see this as a bug, but it would be a nice-to-have feature for the future.
Best regards,
