There is a new Sidekick library plugin project that has a lot more features that we should migrate to to make it easy for authors to create content Code: https://github.com/adobe/franklin-sidekick-library Preview: https://main--rosalind-boilerplate--dylandepass.hlx.live/tools/sidekick/library.html?plugin=blocks

Ooh this looks slick, I will refrain from library updates until you've added it in.
