It would be FANTASTIC to have an official DDB add-on for Google Docs and Google Sheets. As I've noticed even Adam using for his Dev Updates, many people use these online Google tools for their campaign management. Character lists, monster lists, item lists, custom encounter listing/building, and everything in between, being able to link in a specific item/monster/character (possibly a stat block) would be a wonderful way of combining the huge benefits of DDB with the outside campaign management tools we require as DMs.
