Threads Page Transitions via Principle

I've been challenging myself with animation exercises so that I can explore several software programs to see what best fits my design workflow.

I've been using Principle since it's been fairly adaptable with Bohemian Sketch assets. I've used a design app concept of mine, Threads, which enables to catalog and organize your closet to assemble daily and personable outfits based on your mood, occasion, or curated tastes.

I'm loving experimenting with page transitions - specifically timing by the micro-second to make it feel just right - and optimizing how to get Sketch designs faster into animation prototypes for task testing.

If anyone knows of any useful (i.e., advanced) tutorials outside of Principle's website, please let me know and thanks!
