The speed control button on Android is very clumsy. First of all, the area that needs to be tapped is very small, and easily missed by your finger. Second, if I want to slow it down by 0.25 (i.e. from 1.5x to 1.25x), I have to cycle through all the speeds to get back to 1.25x. A simple slider with a larger area to grab with your finger would suffice.
Thanks for adding a speed control in the first place, it is very helpful when the speaker is very slow!
