More control & customization of ticketing emails

I'm sure the community can come up with more thoughts here, but a few that come to mind just while setting this up:

1. Which emails get sent

2. Titles of the emails

3. Some email design control (ie I use a white logo for our knowledge base, but that is barely noticeable on the email. So either the option to use our dark version logo OR a header color in the email)

4. Maybe even heading control, or before/after content options.

5. Footer notice control
