autocomplete-plus | View and insert possible completions in the editor | Autocomplete library

I'm looking to remove/modify the autocomplete-plus package that is bundled together with atom on install.

After a while of struggling and failing, I come to the wisdom of stack-overflow for how I can either:

1. Modify behaviour of autocomplete-plus
2. prevent it from loading in the first place (i.e. remove it from the bundle)

More specifically: how can I choose which order packages' autocomplete suggestions are displayed in?

Here is an example of autocomplete+'s suggestions when using the atom-typescript package:

and one when not:

I want the if snippet shown in the latter image to also come first when using other packages such as the aforementioned typescript package.

I know that "suggestions are calculated using fuzzaldrin", but also that the scoring is customizable to an extent using atom's config.cson file through the useAlternateScoring property among others.

Okay. So Atom installs autocomplete-plus by default. Its quite helpful when I write code, but for example it writes std::cout << "/* message */" << '\n'; when I write cout, but I want it to write std::cout << "/* message */" << std::endl, cause there is a difference between those two, the second one flushes the buffer. How can I make it work my way?
