It would be great to be able to create an appointment from a text string. Many event descriptions are provided as text on websites. They are typically written as e.g. "Music Concert, 20:00, Great Music Hall, Example Street 7, 112233 City". Proton calender could extract the details after using share text with proton calender app in your browser and put it into a draft of a new appointment. This draft can then be manually be checked, edited, and saved.
