It's not at all clear visually which lists are collapsible; e.g. "Main" is
red but not collapsible, "ØMQ Community" is black but not collapsible, the
others are red and collapsible.

Could you use consistent colors and also maybe add a visual hint such as
">>/vv" or similar indicating what is/isn't collapsible/collapsed?

Thanks,
