button - to clean staging playlist

[lslenders]

At this point the interface allows the user to select songs from the tab "The plots". The selected songs are then shown in a list form in the tab "Staging playlist". However, one is forced to restart the whole process of logging in to clear the Staging playlist content. There is no option to multi-select and toggle do-not-save-this-in-playlist.
A button like the bin-icon presented in the tab "the plot" would be useful to have in the tab "Staging playlist" as well.
