I wonder how easy/difficult it would be to take this data:
https://docs.google.com/spreadsheets/d/1F1JdmOflfk8W6WrcpIQVUPubqTCHGOAIXI5eLpR1YEk/htmlview?sle=true#
… and marry it up with qmap.pub. This would provide new, important information that I believe may be relevant to each Q breadcrumb.
With each breadcrumb would be a link for "recommended reading" or "referenced literature." This could expand research and add additional context to the breadcrumbs.
