A small update to SpotifyStatusApplet has been released as a beta.
This version fixes a critical issue with newer versions of Spotify that prevent the applet from working. Thanks JeffreyO.
It also adds the (much requested) feature of playback control using the remaining soft keys: 2 – previous, 3 – play/pause toggle, 4 – next. Thanks JeffreyO.
More information is available on the Project Page.
