New button highlight colour for KitKat

[pushbit]

Currently the button highlights when pressed are the old Holo blue colour. It would be nice to also have the new Holo gray colour when running on KitKat.

Well, I might support customize style in next version, and you can feel free to change the UI then. so far, no estimation about the implementation yet. If this is a hurry need for you, you could fork and modify it. If I remember correctly, there is a fork implement the KitKat UI style, you can check it out by yourself.
