polybarers seem to meet and exchange info here
https://www.reddit.com/r/Polybar
When I fist tried it was driving me mad because the most basic of info wasn't there, what defines the bar that starts. It ended up being "main" defined in the standard conf file as "the" bar.
It all started coming back to me after I installed it again to see the issue, I am surprised people will put so much effort into something like this. I just don't get it. Sorry, no judgement here, it must be part of my autism.
