NI Kontakt: Instruments, Under the Hood, Scripts, Advice, Other Nonsense

Have been spending some time learning how to use Kontakt (5) and am getting more comfortable with it; but, the more I use it, the more I'm realizing that I'm only using like 5% of its capabilities. Feeling kinda overwhelmed.

Any tips/tricks/tut-vids/things you wish you'd known earlier? Instruments / effects you use constantly? Workflow/organization suggestions?

For example (and I have no idea if there's a better way to make custom Kontakt Libraries), using this method to get Libraries to load up has saved me a ton of time: http://iatkos.me/forum/viewtopic.php?t=19045#p72306

Over ten years into Kontakt and still, STILL, upgrading to the new version is a PITFA.
