@@ -453,6 +453,7 @@ Primary causes identified:
   - **New-release alerts:** periodic check for new albums/singles by followed artists (sources: iTunes lookup / MusicBrainz / Last.fm), surfaced in the existing in-app notification bell (and optionally push).
   - **Concert alerts:** reuse the existing **Ticketmaster** events integration to notify when a followed artist has nearby/upcoming shows.
   - Ties into the importer: a "download this new release" action straight from the notification.
+- **Android** — **Swipe between Erkunden sub-tabs** — a left/right swipe gesture on the Erkunden tab to switch between "Bibliothek" and "Global" search (instead of only tapping the chips). A fun, natural pager-style gesture (e.g. HorizontalPager).
 - **Android** — Playlist drag-and-drop / sort order
 - **Android** — Artist page iTunes fallback (for artists not in Navidrome)
 - **Android** — Romaji / Japanese sort support
