The option to use single line spacing rather than 1.5 or 2 only.
YES. The ability to have more control over the text field in general would be AMAZING. More size options, spacing, font color, etc. Similar to what is available to edit this text field, actually!
Per the first comment about line spacing - you can do single lines by doing what's called a "soft return" - hold down your shift key while hitting return and you'll get a single line space!

You're so welcome. :)
