First impression is that this is insanely fast and is actually giving recommendations based on context, without setting up additional files. So, it's doing exactly as advertised.

I'm using this in Vim and would like to know if there's a way to configure it such that the dropdown does not show up until I hit <C-n> or <C-p>? I realize that this is supposed to be a zero-config tool, and I'm asking for a configuration!

Great job with pricing as well. Going to use this for a week before I commit to the license but $29 is a no-brainer for how much use I'll get out of this autocomplete.
