Hi , I'm building my first app. What features, functionality , information should the app's admin panel provide? I'm building a music app that streams music. I guess I need a set up a website and hosting for admin purposes ? ..correct? Is there an online example of a backend admin panel for an app I can see to get a feel for what I require? If I don't end up having an admin, will this cause trouble and issues later on? How necessary is it to have one. Thanks for your input
