I would like to suggest changing the current pitch adjust buttons in performance mode back to actual sliders (similar to CDJ's and turntables). The current method of single tick click a button up and down makes it near impossible to make adjustments on the fly when not using a dj controller or connected dvs equipment. It is also very difficult to click on the pitch bend buttons as they are tiny when using 2 deck horizontal mode. 

If screen real-estate is an issue, another thought would be to incorporate up and down dragging to adjust pitch while clicking and holding down on the main bpm window. This would be similar to Serato DJ. Again, the click tick buttons just aren't quick enough to change bpm while in the mix.
