[Auth] Add Alphabetical Scroll Bar for Easier Navigation

[NotHugo37]

Hi team,

I’d like to suggest adding an alphabetical scroll bar (A-Z index) to make it easier to navigate long lists.

This feature would improve usability and enhance accessibility by allowing quick jumps to specific letters and reduce excessive scrolling. It could be implemented as a vertical sidebar or an overlay that appears when scrolling through long lists.

Would this be feasible to consider for a future update?

Thanks for your attention and great work on the project!
