Here's a mid-thought observation: your IPTV Reseller Panel decides the order of channel categories. Alphabetical? Custom? Random? I've watched a British IPTV reseller lose a sports fan because "Football" was category #47, buried below "Fashion TV" and "Fishing." The customer assumed the service had no football. The panel allowed zero category reordering. The reseller couldn't fix it.
The pattern that keeps showing up is rigid taxonomy. A serious panel lets you drag and drop category order. Run a British IPTV channel list through your panel. Can you put your most popular genres at the top? Can you hide empty categories? One reseller I know reorders his categories every quarter based on viewing data. His IPTV Reseller Panel remembers each customer's last-used category too. That's personalization. That said, many panels treat category order as a database query result. "It's alphabetical because that's how SQL returns it." That's not a technical limitation. That's laziness. Demand control over how customers navigate your service.
