Brainstorming on agenda themes

Hello all,

As agreed, I've copied over my rough list of potential themes to a
discussion issue:
https://github.com/Maps4HTML/Maps4HTML-Workshop-2020/issues/50

Please offer suggested improvements before next week's call!

Also, a reminder that there is an open discussion about improving the
sponsorship page:

Best,
Amelia BR
