Continuing the discussion from Add new note with single tap on iOS:
This would help implementing sharing widget and speed up collecting notes / attachments / todos.
For instance, on macOS/iOS: Share (on anything) -> Agenda. and it automatically falls into Inbox as an attachment or a note, where I can review and organize things later. Same goes for quickly creating notes on iOS via 3d touch, it also could be implemented via some global shortcut on macOS.
