There is a tag “parts submit” and “parts help” available in the forum but many people seems to produce also breakout boards.
That category of design is not not easy to locate yet.
Suggestion therefore is to introduce this category “Breakout boards” as option.
“Breakout boards help” when board is in development.
“Breakout boards submit” when board is ready for final usage.
No idea. I am not current on what all needs to be fixed/implemented, how complex it is, or how much time people with that information (and skills) have to dedicate to it.
