Add category browsing, a two-column Recently Added grid, and a dedicated download queue. Keep compact navigation icons and their animations aligned with the active tab.

Keep profile avatars circular and report lyric enrichment outcomes accurately, preserving existing lyrics and supporting instrumental markers.
