I absolutely concur to @Davey126
's correct statement and recommendation, and I'm unable to add anything substantial. However, I like to share my settings (please refer to attached screenshots), and if interested and required I'll provide information, which of my applications are not greenified.
Regarding your question, at least from my point of view all settings are pretty well explained within Greenify but it's also worth to study the threads by @oasisfeng
that are pinned to this Greenify forum.
