My Bowlet "Classic Clean" is now updated and includes controls and a progress indicator. Click on the cover to toggle the controls. They'll fade out automatically after 5 seconds of inactivity.
I hope you like the new version as many people requested the controls.A bug where the play button would not work has been fixed. The download is updated and I recommend you snatch that update.
