If you'd like to customise the default playlists in Equator2 by removing presets, here's how to do it.
Open the Edit Playlist view then choose the playlist from the drop-down menu on the right.
Click the duplicate button to save a copy of the playlist.
Right-click on the preset and click 'Remove from playlist'
The preset will be removed from this copied version of the playlist.
Feel free to edit the playlist name (click the pencil icon) so you know which one is which.
