Feature Suggestion: Min/Max Range Values for Offset & Shell commands

If you're not particularly paying attention to the scale of your model, then you don't know where begin when plugging in values for "Offset" and "Shell"... I often have to try several values just to get one that successfully displays a result on the screen.

Would it be possible for MoI to display the Upper and Lower Limits of possible offsets by default, or perhaps provide a "Calculate Min/Max" Offset button? (Obviously you would need to cap the MIN/MAX values well before infinity for very simple surfaces that have virtually nothing limiting how far they can go.)

Also, if MIN / MAX values are present, perhaps a range "slider" could be provided at the bottom of the keypad so one can simply slide between the values to evaluate different distances or thicknesses. With a range slider, you would probably need to provide a little "Calculate" button so that MoI didn't try to calculate the offset or shell operation each time you nudged the slider...)
