+1 to the sentiment for the database connector …even though I’m a long way from making good use of it. 
Also +1 to the Mongo connector and to the Google Drive connector that Jeremy indicated is in the pipeline. These would be immense. I am also excited about future of using Observable secrets to learn how to write to databases.
I really see great value and potential in Observable to deepen people’s capacity to make and share applications for data retrieval, analysis and reporting. You certainly have helped me to learn. Huge thanks to the Observable team!
