Why next/prev. buttons are disabled?

Poweramp has 2 types of "next/prev." buttons. The <<  >> (track change) are the "usual" buttons which change tracks. These are never disabled.

Poweramp v3: buttons depend on skin and skin settings, check Poweramp settings => Look and Feel => Skin options (Pro Buttons option or similar in 3rd party skins).

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 is one such list in its category)

Poweramp v3: next/prev. category gesture (drag track a bit more to the side) is available on last/first track in both main player screen in in miniplayer on the bottom on other screens.
