Adds essential highlight functionality to Thunderbird's compose window. Very easy to use, click on "Mark" to highlight selected text, hold down "shift" while clicking undoes the highlight.
This is what should replace Tunderbird's useless "Choose color for background" in the compose window.

This review is for a previous version of the add-on (6.1.0).
