found a bug! an excellent addon otherwise Rated 4 out of 5 stars

This is a very good plugin. It changes the entire face of the compose window. however, I seem to have found 1 critical bug.

When i write something and leave a space at the end, users using outlook and MS exchange mailboxes, seem to pickup a space in html format,( &nbsp). This is very annoying . I think this should be fixed .
This happens for new emails and also any email that I am replying to.

Feature request: Please add functionality to allow choosing fonts from all available fonts in the system

This review is for a previous version of the add-on (0.2pre).
