Feature request: Zoom editable from Navigation window

[Jakeukalane]

When using zoom (previously marked F6) in Navigation window, the steps are usually too high and I have to send the parameters I'm using into main windown and then to position and correct the zoom number. A good thing would be to be able to edit the zoom like any other value of the navi, doing double click with the mouse and set the number.

Thank you

I agree that this would be useful, will add it in the next release
