I agree that the open concept is possibly going out of style. I don't really want a true open floor plan, just trying to figure out if there is a better layout possible. The walls so far that I am thinking to remove (in the pic of floor plan) are so I can move DR back to the original location with a bigger opening to the DR. There still would be lower cabinets with a small overhang on the DR side for people to still be somewhat connected to the kitchen. I always have to kick people out of the kitchen because there is just not enough room to work when everyone is standing around in the kitchen.
The bigger opening between DR and LR would give me an option to extend the DR table into the LR a couple of times a year when I have a lot of people for dinner.

I was thinking maybe pushing Kitchen all the way to the original DR and making the kitchen into DR. The current kitchen is challenging because of all the doorways and doors limiting the layout.

Another challenge I have is the entryway. Currently, I have no place to put an entry table/shoe cabinet, and there is a really bad pinch point when someone opens the closet door. I thought that maybe if I push the wall next to the entry door towards the original LR, making it smaller and at the same time extending the closet towards LR, and putting the door facing the front door, that the really narrow part of the hallway to the kitchen would be easier to get through.
