### Pain

The playlist that was created was left without an image, too lazy to add it manually either from local or link.

### Suggested Solution


Add options like "set image as playlist image" at the three dots.

Algorithm to prevent bugs:
- Show options only when open a playlist and song are in a playlist
- Show options only when the song has an image/thumbnail and meet the requirements
- The playlist referred to is only the playlist that is opened
- If the song used as the playlist image is deleted or moved, delete the playlist image as well and leave it blank
