I often like to include screenshots when explaining how to resolve an issue and it lets me add the picture inline in the notes section but it doesn't show up in the email that is sent. Users need to be able to see it in the email--they often don't go into the interface to view any notes... they only look at the email.
Also, a little icon to attach a photo, or add inline in the comment.
Couldn't agree more - it saddens me that this isn't natively supported. I often use the snipping tool to record GIF's walking folks through the steps to fix their issue. NEED THIS!
