Re: Back annotate references from PCB
Hi,
thanks for answers!
Brian, I will definitely like to give a hand. But before start
everything I need to study things guys talking about. I haven't really
look about KIWAY yet. Probably after that I will have more clear look
how to implement that.
And many thanks for suggestions and advices.

I don't know where he is with porting it into the KiCad codebase right now, but you should definitely reach out to him and coordinate work so that you don't duplicate effort.
