This is an excellent app. the combination with gpodder makes it my must used application of the N900. I just noticed that its seems to pulse alot when am changing orientation from portrait to landscape and vis versa ( It also pulses when I change the orientation of other application like the phone app, gpodder etc), I also experience pulse when I lock the screen. Not by any means a deal breaker. But solving this bugs would go a long way to improve user experience.
