A: Thanks for the questions Sumoling-brandz.
1) Would Parallax effects still work?
Parallax effects and other items created with JS and CSS should work great in the static environment produced by Simply Static.

2) What about Gutenberg animation effects? EG. Fade in?
Animation effects add using the Gutenberg Block editor should also work as they do not need a dynamic environment like PHP code

3) Any plans for real time sync and updates from WP to Static?
We are always adding new exciting features to Simply Static but real time sync is not currently on the roadmap. You can currently set your own export schedule using some of the great WordPress hooks included with Simply Static and by using WP-Cron. https://simplystatic.com/docs/running-simply-static-with-wp-cron/
