Thanks for the suggestions!

I got quite a bit of feedback about the layouts, via various messages. We probably will just go ahead and leave the living room as-is, since you think that works.

I also took some of the ideas and put together a new layout for the downstairs room with the fireplace. I grouped the seating around the fireplace so that is the main focus, but replaced the 2 chairs with a padded ottoman, so that people can sit either facing the fireplace or the TV (and the TV is not blocked from the love seat, either). Is this one better?

same layout but with a glass desk on one wall
