[Feature request] scroll inside price textbox to adjust the numbers up and down

First of all let me say great work from the team. you keep delivering this amazing features we want more.
It would be very handy to be able to modify the price with the minimum domination up and down using the mouse wheel.

  1. click on price in the book
  2. click inside the price textbox.
  3. scroll up to increase the price, scroll down to decrease it.
    current user steps are too many compared to using the scroll.
