Is it possible to have folders or something in the presentation area so that we can organize the presentations? Once you have 20+ it is hard to manage without some kind of folders for each client or schedule.
Not a full solution, but if you practice effective naming for your presentations you can use the search feature as a pseudo folder system. I have about 40 live presentations right now (many feed into other presentations which in turn feed to live displays). I title all related presentations with a common starting word so that I can search for that word to see only presentations related to that display.
The system isn't perfect as the search criteria is lost when you return to the full list of presentations, but it can help to better organize your presentations once you start accumulating more and more of them.
