Your channel layout is controlled by the player app, so you can tailor it without affecting your subscription.
Create favourites
In TiviMate or IPTV Smarters, long-press (or select the star on) any channel to add it to Favourites, then set Favourites as your default view.
Hide groups you don't watch
In the player settings, open "Groups" or "Categories" and toggle off the ones you never use (e.g. international channels) for a cleaner guide.
Reorder categories
Most players let you drag categories into your preferred order in settings. Changes are local to that device.
