| 1083 | Desired behavior for prev/next/shuffle: |
| 1084 | |
| 1085 | - NEXT will move to the next track in the list when not shuffling, and to |
| 1086 | a track randomly picked from the not-yet-played tracks when shuffling. |
| 1087 | If all tracks have already been played, pick from the full set, but |
| 1088 | avoid picking the previously played track if possible. |
| 1089 | - when shuffling, PREV will go to the previously played track. Hitting PREV |
| 1090 | again will go to the track played before that, etc. When the start of the |
| 1091 | history has been reached, PREV is a no-op. |
| 1092 | When not shuffling, PREV will go to the sequentially previous track (the |
| 1093 | difference with the shuffle-case is mainly that when not shuffling, the |
| 1094 | user can back up to tracks that are not in the history). |
| 1095 | |
| 1096 | Example: |
| 1097 | When playing an album with 10 tracks from the start, and enabling shuffle |
| 1098 | while playing track 5, the remaining tracks (6-10) will be shuffled, e.g. |
| 1099 | the final play order might be 1-2-3-4-5-8-10-6-9-7. |
| 1100 | When hitting 'prev' 8 times while playing track 7 in this example, the |
| 1101 | user will go to tracks 9-6-10-8-5-4-3-2. If the user then hits 'next', |
| 1102 | a random track will be picked again. If at any time user disables shuffling |
| 1103 | the next/previous track will be picked in sequential order again. |
