Do you except feature requests?

I require something which could be called doubleExponentialSpinBox. That should be a SpinBox that excepts double values but displays them as "1234.0234 e -123".
The Buttons should then increase either the value or the exponential depending on the position of the cursor.
I require this very often since I am a physicist and deal with high exponential values quite often. However it is not possible to display these in any standard spinbox.
