Charming home! Have you checked to see if the wall is load bearing? A wider trimmed opening could be lovely. I think you probably have too much furniture in the LR and some of it is too large.

Thank you. The wall is not load bearing and has solid pocket doors that come out on either side of the opening. The house is over 100 years old so many renovations were done before we moved in! Which items of furniture should I remove/change?

I think a detailed floor plan would be helpful here . I am not sure that opening the wall more would help anything but certainly if it is not load bearing it would be easy to do other than replacing flooring. Since the space is small maybe rethink the size of your furniture and remove the furniture you do not need . IMO the bookcases just look cluttered and the chest beside them just adds to the clutter. BTW when hanging mirrors always make sure what they reflect is something you want to see twice.I love the stained glass in the windows but hate the center light fixture, I almost never like center lights in LRs they cast shadows in the weirdest spots . I think the buffet piece in the DR looks like a bathroom vanity so I would put the pices from beside the bookcase there instead. As for covering the fireplace I think what is there now suits the space.

Thanks for your comments -- the fixture was there when we moved in and we were considering installing potlights in the living room. Do you think this is a better option for that room? It is darker because of a large porch at the front of the house. The mirror on the wall was put there to reflect the light that comes into the room from the exterior window that it faces...

The bookcase is built-in so not easy to remove but I will def edit the contents so it doesn't appear cluttered!

I agree with Patricia, you have a lovely home, Monicawhitten. The wall with the pocket doors could still be load-bearing. The pocket opening is likely framed with a header carrying the load from above and transferring it to the floor joists or whatever supports are below. My unprofessional opinion is it would be relatively easy to remove the pocket doors and reframe the opening utilizing the existing header. I'm not saying I would recommend doing that, especially if the pocket doors are original to the home. I'm merely suggesting a simple means to open doorway between the rooms. The opening you described would involve a longer and maybe taller header, ie much more work.
