推理
用户这次有三项修改需求：
1. 底部导航「推荐」按钮改为「首页」
2. 子曲谱视图的信息栏中：移除作者信息、加入导入按钮
3. 曲目操作菜单中：删除评论和点赞按钮、增加置顶按钮、增加排序下拉菜单
让我逐一处理：
1. 底部导航：把「推荐」改成「首页」，图标可以考虑用 fa-house，保持曲库在右侧不变
2. 子曲谱视图 sub-header 中移除 lib-author 行，加入一个导入按钮（可以用加号图标，类似新增曲库的样式但小一点放在信息栏右侧）
3. 曲目操作弹窗：删除评论和点赞行，增加「置顶」和「排序方式」两个选项，排序点击后展开子菜单（按名称/按时间/按热度等）
我来整理这些改动并输出完整代码。注意保持现有配色和风格不变。
关于排序按钮，我可以设计成点击「排序方式」后弹出二级菜单（或者在同一弹窗中展开更多选项），也可以做成下拉子菜单。考虑到移动端体验，我在弹窗中「排序方式」项点击后替换为排序选项列表（按名称排序/按时间排序/按热度排序/按手动排序），这样比较自然。
导入按钮就放在 sub-info 区域，用一个小型按钮，文字"导入曲谱"加图标，放在曲目数下方或右侧。
