We went through Peter's course - https://www.udemy.com/course/kicad-like-a-pro-2e/
Well worth the money.
Thank you for mentioning it. I started the course this morning and so far, I'm very content with it.
We have to make the transition from Eagle V7 to Kicad and this course gives me a kickstart.
edit:
I finished 2/3 of the course and I felt confident enough to start with a project. Before starting with commercial projects,
I'll start with a hobby project to see if any showstoppers come up.
First little job was to write a script (ULP) that mass converts the generic devices (RLC) in my custom Eagle library to a Kicad symbol library.
