One kitchen feature that I would love is a concealed shelf for a stand mixer that emerges and rises to counter height. Complete with plug. I saw this recently at a friend's home.
The people who had the over-the-refrigerator-drawers-turned-sideways also had the concealed stand mixer set-up you describe.
They had a giant drawer full of occasional use items - such as a blender - that were also complete with the powered plug-ins. Just reach in and set on counter, use, clean, and shove back into drawer.
A lot of thought had gone into the rest of the cabinetry. Such as:
... a large (5 or 6 ft?) pullout that had canned goods on one side, and a skinny place for broom and dust pan on the other side
...vertical spaces in a cupboard over the oven for cookie sheets
...lengths of motion-detector activated LED light tape up under the toe-kick areas. Walk into the kitchen at night and you can see where you're going without having to flip a switch anywhere
...small glass-front doors at the very top that were LED lighted
...very smooth contoured drawer and door pulls that are "bruise-free"
...more big drawers for pots and pans
Another area (stairs) also had motion-detector activated stair lighting.
