Must Add Features!!

Amazing website one of a kind! Please add the following though it would be the perfect website.

1. Layout/Interface themes that are more modern looking. I hate the background and the squarish look of everything it looks old so giving some new fresh themes would be great
2. View modes. Let us see playlists in different ways so like list view, tile view (where its like now but multiple next to each other in tiles), etc...
3. Note-taking options to take notes with formatting
4. More filtering options by type, language, keywords/tags etc...
