Hello,
I have noticed that when including two bar buttons, one on left and one right the hit area for the left button expands too close to the middle and I believe it will affect the users dragging up experience. Also, since its a music control it will also cause people to pause music when they think they are expanding. I am especially concerned for my fitness app because that could affect someones workout.
I have tested on multiple iPhone sims, here is a screenshot on an iPhone 5 with the left limit of hit pointed out.

Interesting issue. It's something normally controlled by the system, but I will take a look.
Fixed this in 2.0.3. Please upgrade your version and test. 馃槃
