I'm looking for suggestions for the layout of our living room. A diagram with measurements is attached (each square of the grid is one foot). We have a lot of doorways and all of them are utilized, although the door in the upper left is used the least and could possibly be closed off (just close the door). The doorway on the bottom side is the one we use the most -- it leads to bedrooms upstairs and to the kitchen. The french doors to the right head towards the dining room and also the exterior doorway into the house.

Currently we have 2 chairs on either side of fireplace and a sofa opposite that (a few feet in front of the french doors). Our TV is between the windows. We have a 9x12 rug. We don't love our current furniture so we're open to any and all suggestions. Thank you!
