検索機能に新しく追加した曲リスト!
で、一瞬凄く喜んだんですが、なかなかに微妙な機能な模様・・・

1. イニシャルサーチ
日本語の場合ローマ字入力の1文字目だけで検索
2文字目を入れると日本語は検索対象外に
「S」を入力すると「S、さ、し、す、せ、そ」で始まる曲検索され、「SA」と入力すると「SA」始まる曲が検索されるってことか

3. 最近追加された曲リスト
そのまんま追加した曲がどんどんリストに並ぶだけな模様
削除は手動で
追加日時でアルバムがソートされるもんだとぬか喜び(;´Д`)

Cayin N8のファームウエアアップデートは致命的な問題が無い限りこれで終了だそうですよ
一応ピンイン順が使いにくいって事は認識してるみたいだったんですがね・・・
