I've made by myself a widget using Tasker to make some intent to Poweramp API + KWGT for the graphic interface.
In this way I'm able to move quickly from shuffle all to shuffle artist to album to last added...
Why do not provide such similar function in the application?
Because the screen recorded video is bigger than the limit to upload, I cannot attach a sample.
If you want to see it, do not esitate to ask me
