REQUEST: Add source of documentation

[HayDegha0917]

When the selection under the cursor is ambiguous, it would be nice to list the origin of each possible entry. For example, if I click on the word "set" in the code

function foo() { _.set(...); }

I get the attached list, which is less than obvious. Even though the icons provide a hint, Adding something like:

lodash 4: set

would make it clearer.
