title: Automatically open default email client and pre-populate content
body: <p>I need to automatically open a user's default email client when they save some content on a page. I need to populate the email subject, to address, and put some content in the email body.</p>
  
  <p>What is the best option to achieve this?</p>
  
  <p>I'm aware of the <code>mailto:</code> attribute, but the user must click on this and I'm not sure it allows you to specifiy the subject and content?</p>
