enhancementfeature: previews and thumbnailshelp wantedperformance 🚀

Description

Scenario: 4 years with ~200 folders and ~50 images per folder. After a fresh installation I want to quickly show an image. But after navigate to the desired folder it took long to get all thumbnails (in list/grid view).

Research how

  • other do that
  • store the newest (now) 1000 (or more) thumbnails
  • add "download thumbnail" button
  • how to deal with limited cache?

I am open for any discussion :-)

Research direction
Investigate how other apps handle thumbnail caching (e.g., using disk cache for recent thumbnails). Look at Nextcloud Android app's current thumbnail loading in the gallery and file list views. Consider implementing a 'download thumbnail' button and a configurable cache size. Review existing PRs or comments for potential solutions.
