About this Add-on
Yes, these are what this add-on do! You can change the view mode temporarily without changing the default setting, and you can reply a message with full HTML of the original message.
Also that you can forward or print a message in HTML mode temporarily, but there is a bug in Thunderbird(https://bugzilla.mozilla.org/show_bug.cgi?id=228562),
so that when your default setting is "compose message as Plan Text", foward will not work well, I just add this function and wait for the fix from Thunderbird...(fixed in 3.0)
Thunderbird 3.0 compatible new version 1.0.2 released, you can download from here or the homepage below.
