The Pro version allows you to add comments and start a conversation with your teammates about any of your to-dos. You can leave feedback, ask a question, or add extra insight. Attach files including photos, spreadsheets, presentation decks, PDFs, videos, and even sound bites to any list. Assign lists to colleagues to delegate responsibility and keep team activities on track.
