recessed kitchen pass-through...can add between wall studs
island with overhang for seating along with extra prep sink and storage under counter on both sides
Stepped down counter for more comfortable seated level while eating. Like that better than climbing up on stools.
Center pedestal leg on lowered counter for seating prevents a lot of run-ins with peoples legs or knees.
Add similar utility area on a smaller scale to wall in kitchen that backs up to garage and just around the corner from the entry into kitchen from the garage.
bookcases for cookbook collection, option to close off to keep smells in the kitchen or close off noise of kitchen from quiet needed in next rooms
pass-through from kitchen to patio saves a lot of in/out travel, bugs, etc.
storage capacity yet easy to pass items through from kitchen to dining room
Swinging door between kitchen and family room to block ou noise and smells. Like the idea of having glass inserts (not mirrors) so that oncoming traffic can be seen.
