Pretty little feature my worker

Add a way to remove files when it's push up into the playlist. I probably will do a pull requests if I had time xd.

Also when I push up the same file to the program it added again. Another feature or issue I'd say.

Also multiply by 2. I was using it between 1h and 3h in the background(e.g program&) and suddenly the visualization disappear when I add another song.

Also multiply by 3. It's tedious always drag and drop why not do another option like drop a file that content a list of paths like: "path1","path2","path3"; And drop like a song by this time add all them to the playlist.
