I use thunderbird too. If you right click on the server name
and then go to "Settings" -> "Composition & Addressing"
and then uncheck "Compose messages in HTML format"
I think that should do the trick.

Ack.

sysfs APIs typically have a one file per setting approach,
so for effects with speed and multiple-color settings you
would need a whole bunch of different files and then you
would either need to immediately apply every setting,
needing multiple writes to the hw for a single effect
update, or have some sort of "commit" sysfs attribute.
With ioctls you can simply provide all the settings
in one call, which is why I suggested using ioctls.
