Add a "play in mono" option
Some podcasts are recorded in stereo which can drive you crazy while listening with in-ears or can make it impossible to understand all if you only use one in-ear, e.g. on the bicycle. So the possibility to play everything in mono would be very helpful

One tip: I use a Plantronics BackBeat Fit. It is an bluetooth headphone optimized for sports. It keeps the ear open, so that you can hear everything around you. I use it for running, racing bike, mountain biking and — most important — biking to work: 34 km each day in heavy Berlin traffic.
