As for <<< >>> (list change) these can be disabled when there is no list to change, i.e. there is just one list in such category, for example:
- when All Songs list played or Shuffle All mode enabled (all songs played, no way to change list to another "all songs")
- when Queue is played (there is one queue, not possible to change to other queues).
- when Recently Added/Top Rated/Most Played/Recently Played lists are played (there are one such list in their categories)
Poweramp also supports up/down swipes over album art to change the lists.
