Scroll bar for media viewer

Hi,
I'd like to request a feature for the media viewer in the Nextcloud Android app.

Currently, scrolling through photos or videos is slow and lacks context, there's no way to quickly navigate by date or get a sense of where you are in the timeline.

What I’m looking for is:

A fast scroll bar on the side when viewing media (especially in large folders)

A floating date indicator while scrolling (like “June 2023”)

This is imilar to what exists in Google Photos, Google Drive, MEGA, and most cloud gallery apps

This would make browsing large media libraries much faster and more user-friendly.

Thanks in advance — I really appreciate all the work going into the app!
