PLEASE can someone develop a scaling add-on for Inkscape? I would like to be able to set the size of objects, and to see their sizes in user units rather than pixels or mm. It would just need a feature for the user to set his scale, i.e. how many user units = how many pixels and I suppose what is the user unit called. Then all the UI could show in user units. Coreldraw used to have a feature which did this quite well (I don't know whether it still does). This would make Inkscape much easier to use for CAD or architectural design or garden design. Or if no-one wants to do it please explain how I learn enough to do this myself.
What I presume you seek are custom document controls where you can set a custom unit identifier (ft, m, or "Rowans", etc.) and set the scale to Inkscape's (SVG's) internal user-units.

It's complicated...
Firstly, there is already an SVG defined term "user units", which are what Inkscape uses internally to set scale.
User units determine scale via the viewbox values ratio to document width and height.
