[1.56] Slider price adjustment

Its very difficult to set a precise price with the slider because the resolution is so great, a couple of pixels movement of the mouse changes the price. Can we have both the slider (for coarse moves) and some <+> and <-> buttons to fine tune it in single steps?

I had the same issue but I reduced the mouse sensity in order to set the price I wanted.

But I like the idea to have buttons and the slider.
