Here was his interview, felt like my computer screen, lol: https://wp-content.co/wibowo-sulistio/

He says the best way to learn is to get make a version of something that already exists. He has a Floating Share Button and a Floating Scroll To Top Button.

I will release my widgets as downloads then. Free ones and then premium ones.
