Need all the dimensions on a scaled floor plan. Pictures of the room would help as well.

Dimensions of the room and your furniture would help a lot. My thoughts are to move your table to the wall where you have the bookcase with the shorter side against the wall. That would give your dining and seating parts of the room more separation. Put the bookcase on the wall where the table is in your drawing. I don't think a corner desk works best in this room. Look for a smaller narrower one to put behind the sectional giving you somewhere to put lighting. move the sectional further down just enough so you can just walk behind it to use the desk. The tv can stay where it is but the sectional shouldn't extend much beyond it to give you space to move around everything. Your floor to ceiling window shouldn't have anything in front if it unless you'd like to bring in some living plants to take advantage of the light it brings in

thank you both for your input! Here are some older pics of the room before the dining table and desk.
