@boomerang,
I would love pocket doors between my living room and dining room . . . you enter the house through a small vestibule in front which opens into the stair hall. The living room is on the right as you enter and the stairs rise on the left. The living room, dining room and kitchen all form a string to the right, going from front to back.
I would love pocket doors so that I can enclose the living room and take the sheets off the furniture. I recovered my furniture and need to preserve it from cat claws and cat puke. Right now, the furniture is under sheets!
There are things that need to be done that are more important than pocket doors, although they would add beauty to the house and safety to the furniture!
One thing to consider: the installation of pocket doors might mean relocating electrical wires within the walls.
