Editing playlist tracks - use a context menu rather than selection mode
Submitted by Allan Day
Selection mode is best used when in it is typical to act on multiple items simultaneously. When editing tracks that belong to a playlist (such as removing them from the playlist), it is most common to act on individual items.
A context menu on each list row would be better than using selection mode. This would have the added benefit that context menus are less work to use than selection mode - you just right click (or long press) and act directly on the item.
