Hello Robert,
Thank you very much about bringing this to our attention. As of this time this isn't something that we're working on or considering releasing in the near future. However, this is something that we would like to explore and try working on in the future so I'll be sure bring this back to our team and see what we could do about. If you have any future suggestions, you're welcome to suggest them at our UserVoice: https://proclaim.uservoice.com
I think starting with Notes editing would be great.
1. For people to jot down some quick notes that they want to mention when they get up to make their announcement. For things that arent sermons and don't require that level of preparation - or forethought to type it on the desktop - but quicker things that you don't want to forget to say.
2. For "mini-sermons" in the service. Maybe by the worship leader to introduce a song, someone giving a devotional, sharing a verse before the offering, etc. So they will have a way to add in their notes and have them show up on the display on stage.
3. For anyone to be able to add a note for a DIFFERENT person to communicate. Guest names, updated info about an event, last minute change of service schedule so they can introduce it properly, etc.
