maybe makes sense to show a normal weight version of the patch for comparison...
quite less poluted if you ask me, and it's not like I cannot read the patch as well for not being bold too...
I don't really have a strong point, at the same time I also do not think that one is much worse than the other.
I think the comments look better with the regular font but I think it's fine to have the objects as bold. Esp with diff weights of fonts, it's easier to pick out the objects at a quick glance. I think that could be particularly helpful since Pd vanilla (at least without any tcl plugins) doesn't distinguish objects from the rest of the other things on the canvas with different colors or fills.
