User should be able to create an event/meeting from an email's content. When one signs up for webinars, you'll often get an email with details of the event rather than an actual invite. That email will have links to create an event in Outlook, Google, .ics, etc., but clicking those links naturally opens up their respective apps. Would be great if there was a "Create Event from Email" that would try to ascertain event info (date, time, location, and conference #'s/links) from the email and include link to email.
There is a feature request already for "Create calendar event from conversation", but that request is to create an event for collaboration that involves the conversation participants. This already seems to be a feature in Missive in the ... options.
