I find Dropbox Paper quite useful. We're already using it in our office and already see benefits.
However, we're missing a feature. We would like to have possibility to sync tasks defined in paper documents with some calendar apps. It would serve as a daily reminder of tasks that have to be done, and after they are marked as finished in an app, ther status should be updated in relevant Paper document.
I thought that Google Calendar sync had that possibility, but as I discovered it only allows Dropbox Paper to import meeting schedule.
