Add a playlist lock feature to avoid accidental deletion due to phantom touches

a playlist lock feature must be helpful to avoid accidental removal / deletion

This could be very useful! It is something that I thought about for a long time. A toggle switch or something for it to be locked so you cannot edit anything by mistake. Reordering song in playlist or deleting. Maybe a double check if you want to add new songs without unlocking the playlist could also be useful.
