New Email Builder Issues

Here are a few issues I've seen from the new Email Editor, and I wondered if anyone had any workarounds.

1. When I go back into a newly created email from my own template, it's showing HTML code instead of the email. When I click 'Edit email content' to edit the email, it will then show it correctly. Is this a bug, or am I doing something wrong?
2. Can I send a proof if I don't have the access level to see the email as a specific person? Since I can't choose a person from the dropdown list, it won't let me send a test.
   
3. I've created some Fragments to be used like modules did in the past, and have specified that the text and/or image can be editable, but when editing an email, I'm not able to edit anything other than the image or text. Meaning, I'm not able to edit the font size, color, etc. Is there a different approach to this so that the client can drag and drop modules/fragments and edit the font size, color, etc?
