Toolbar spinboxes also have this functionality, but lack the unit stuff.
(where it would be really convenient :(   I will not work on this unit
functionality in the toolbar. Maybe someone else can work on C++-ifying
the "ege action" stuff and widget/toolbar.cpp, a first step on the way
to getting there. In all C++ UI stuff it is easy to add, and let me know
if it is missing somewhere.

In very quick testing

I spent more time looking into this. So, here's my more "exhaustive" list.

Spinbutton math doesn't work:
Preferences>Interface>Zoom correction factor spinbox
Object>Fill & Stroke (all spinboxes)
Object>Rows and Columns (all spinboxes)
Text>SVG Font Editor
Extensions (the ones I tested)
Filters (any customizable filters, presumably because they're just extensions)

Another "polish" observation (since we were talking about this topic recently):
Preferences>Steps has px hardcoded as opposed to configurable units (I could definitely see this being configurable as a very useful feature for technical drawing)
