Feature request

The app is superb, however there are inconvenient issues when I'm using the app:

1. Lack of countries
2. Unable to create our own category for channels
3. Lack of stream media controls
4. Not a proper dark mode (it's blue mode)

It would be great if these features are added:

1. Let us add our own stream link in the meantime and save it
2. Let us make our own categories of channels
3. Add basic media control (volume, brightness, change resolution, pop-up player)
4. Add material you feature
