A good and robust kitchen creator would be excellent, perhaps with a few select hardware objects(Fridge, Sink, oven, stove and so on). Kitchens of course can become incredibly complex and are an entire BIM project in and of themselves. Our office is currently using this really quite excellent plugin https://www.food4rhino.com/app/kitchencreator to do most of the cabinetry. It’s very nice because the geometry is as simple as possible for 2D drawings, yet for renders the corner rounding makes a huge difference and the results are quite excellent for that as well.
Something akin to that with parametric capabilities and the ability to add sinks and stoves would be really practical, at least for our very residential heavy office.
