How many people do you think you will ever seat at your dining room table? For me and the DW it was 2. For that once in a lifetime event when we wanted to set 4 we can do that with tray tables. Think about what you NEED. With the dinette gone we had a table and chairs setup. What we found is that we could get rid of that as well and installed a 2 person bar and bar stools which fits flush against the wall and gives a lot more room and an excellent view our the windows. The couch has been gone for years and was replaced by a free standing cabinet with built-in "fireplace" which left room for my lounge chair which was substantially better than any sofa option.
Whatever you can imagine, you can do. Just figure out what YOU want and then make a plan to make it happen.
