hey there keith,
</p>
<p>
welcome to the openlp.org community!
</p>
<p>
actually openlp.org supports this feature. you can either blank the screen (mute) or you can close slide and keep the background. these features make presentations very easy.
</p>
<p>
just download it and give it a try, it's really easy to use :)
</p>
<p>
be blessed,
</p>
