推理
The user wants several changes:
1. **New library button** - should open a bottom panel (similar to import panel) with fields for cover image URL and library name. Default cover if none provided.
2. **Multi-select mode for bulk delete** - Add a button to enter multi-select mode, where you can select multiple tracks and delete them all at once.
3. **Search should also search by artist name** - The inline search should match both title and artist, and the placeholder hint should reflect this.
4. **Delete option in song popup should be at the bottom** - Move delete to the last position in the action menu.
Let me implement all these changes.
