Looks like there is already a workaround possible for my need to post process on the canvas.
I used this advice.
Thats the result (as long as I stick to OSM naming conventions, I guess)
Now I have at least a quick overview whats going on but the rest of HB still goes separate ways…
One idea that came up,
Maybe it would make sense to offer a check for names according to OSM conventions while editing?
