<p>Thanks for the suggestion and we'll consider it for a future release.</p>
<p>Although they aren't notes in the typical sense, a workaround is to add a custom item to the order of service and put the notes in this, making sure the operator knows not to display them!</p>
<p>Also in our church, I've added some special "songs" to the database with titles such as "-sermon-", "-prayers-", etc. The "-" indicates to the operator to not display it.</p>
