v0.4.0

JellyTunes 0.4.0 — Lyrics, cover art modes, and smarter sync

This release adds lyrics sync, a cover art mode selector, a redesigned sync preview, and a large batch of reliability fixes across selection, storage estimation, and file handling.

What's new

Lyrics sync — JellyTunes can now download .lrc sidecar files or embed lyrics directly into tracks. Works with Jellyfin 10.9+ (JSON format) and older servers (plain .lrc). Orphaned LRC files are cleaned up automatically when you switch modes.

Cover art mode selector — choose between embedded cover art and companion cover.jpg files per device. Your choice is remembered between sessions.

Redesigned sync preview — the preview modal now shows a three-column layout with per-category breakdowns (new / will update / will remove), a total row, and a selection summary with combined duration and estimated size before you start a sync.

Smarter selection — track sizes are estimated as you select, using batched Jellyfin fetches and tick-based sampling. A fetch threshold guard prevents accidental runaway requests on large libraries. Select All now handles pagination correctly on any library size and recovers gracefully from errors.

Per-tab search — Artists, Albums, and Playlists tabs each keep their own independent search query.

Lazy image loading — library cover art loads as rows scroll into view, reducing initial load time on large libraries.

Fixed

• Stale cover.jpg and .lrc files are now cleaned up when switching cover art modes or removing items
• False "out of sync" detections after changing cover art mode
• Disk-full hangs and ghost rows in the sync database during large syncs
• Select All race condition on large libraries
• Storage bar showing inaccurate estimated sizes (~ prefix now shown correctly while loading)
• Sync preview track counts and durations showing undefined in some cases
• Library images disappearing after load in certain scroll positions
• Several LRC file path handling edge cases
