Autocompletion in Sublime Text (3)

Like many here - I love the speed and flexibility of Sublime Text, but my inability to (properly) setup autocompletion absolutely irks me to no end (especially when compared to PHPStorm).

I'm curious if anyone out there has has a competent configuration, and is willing to share it.

Here's an example:

If I'm working on a particular view, and I want to include the form.edit.blade.php file, which is in the resources/views/posts directory and not currently open (I'm aware of the AllAutoComplete plugin) - typing @include('posts. would be enough to trigger the auto_complete window and it would only suggest files that are in the posts directory.
