Very hard to attach screenshots to a new story

In Pivotal Tracker, I could just paste a screenshot in from the clipboard directly into the comments.

In Lite Tracker, I have to create the story and click save because it doesn’t expose the comments field on new stories. Then I have to go back into the story and attach a file because it doesn’t allow me to paste screenshots from the clipboard into the comments.

This is making it really painful to attach screenshots to new stories.
