[Feature] Minor QOL Improvements

[ghost]

Firstly, thank you for the amazing project. If you are unable to fulfill the requests below don't worry, they're just some ideas I came up with to mimic soggfy on linux.

While using the app I thought up a few improvements that could be added to the project:

• Launch Spotify and minimize onthespot. Spotify launch path can be specified in settings and onthespot can record in the background.
• Add download icon in Spotify app to songs that have already been downloaded (see https://github.com/Rafiuth/Soggfy)
  • Skip already downloaded songs in spotify app (see https://github.com/Rafiuth/Soggfy)
