Make the "Project Estimated Start and Finish Date" Required When Editing Lead Info

The Project Estimated Start and Finish Date fields are very important for giving end users a sense of direction regarding a lead. Within the current environment, this field isn't required, leading to potentially misleading or absent information downstream during the life of the lead. Making this a required field could be a simple way to allow the end user to approximate the direction of a lead as seen fit without wasting their time.
