"Invert Snap" (or atleast Enable Snap) for Inset Faces

It would be nice to have Invert Snap for the Thickness in Inset Faces, just like you can temporary toggle snap with Ctrl when you move after triggering extrusions.

Having full on snap functionality like vertex snapping and so on might be a bigger task for insets. Maybe something similar to Enable Snap, like in the Spin tool for instance, might be an easier option for starters. So when you holding Ctrl you snap Thickness to increments or when you hold Ctrl+Shift you snap to Thickness to 1/10th increments.

Depth adjustment could be moved to Alt in my opinion, and could then also be made to work with snapping when combining with Ctrl or Ctrl+Shift, and make Inset Faces behave more like other operations involving moving geometry around, just like extruding or moving in general.

Feel free to comment if I missed something obvious here or my wording is not clear, and I will try to adjust my suggestion accordingly.
