can it show the function's params that in scala libs or users' class functions ?

when i use this plus, i can't get the effect like the idea, it can't show the function's param type! sometimes i input a class name( scala lib's class or my class ) or object name and add a "." after class name, it can't show the functions in this class or object !

Start by reproducing the issue in Atom with a Scala library class and a user-defined class or object, checking both parameter types and member completion after a dot. Trace the language-scala completion and signature-help entry points; done means functions and their parameter types appear for both kinds of classes.
