Feature description

Navigating through a large list of subscriptions in NewPipe can become inefficient, especially when users follow many channels. To improve user experience, I suggest adding an alphabetical scroll bar (similar to what's seen in contact lists or music libraries on Android).

Why do you want this feature?

Faster and more efficient navigation through long subscription lists.

Improved accessibility and usability for users with many subscriptions.

Familiar UX pattern for Android users, making it intuitive to use.

Additional information

This small addition could greatly enhance user navigation and make managing subscriptions more user-friendly, especially for long-time users with extensive lists.
