You need to cross post this question on the GW Home Decorating forum. Those folks should be able to help you. Also, that forum generates more traffic. By the way, good question.

If you want the window as uncovered as possible during the day, I would look into shades that you can raise during the day and lower at night. If you are fine with having some of the window obscured during the day, I would consider Silhouette shades. The sheers protect the interiors from UV light and help bring natural daylight further into the room. Shutters would be a nice look, but I'm concerned about opening and closing the louvers. I'm assuming since you want privacy at night, you will want to keep the window treatments closed at night. If the sofa is going to be sitting in front of the window, you are going to constantly be reaching over the sofa to open and close the louvers. With Silhouettes, you can get a similar look to the shutters, but you can operate them with a cord (which can be placed on the side of the window that is most convenient to reach) or they can be motorized. Silhouette shades also come in wide widths, so you should be able to cover that window with one shade.

Yes we need to open the windows a lot there is no A/C (coastal town, ocean breezes!). We can't have blinds with cords of any sort due to toddler safety and as it turns out there are no cordless blind options I can find in 93" and greater widths. So curtains it is! Good point about the air flow, too! I like a double rod with sheers underneath (there are neighbors behind) and room darkening on top for the bedrooms. Now the question is to have them be just the height of the windows (i.e. Hang rod just over window top and have curtain cone to sill) or visually lengthen by hanging the rods at the ceiling and having curtains go to the floor. I generally prefer that look and will do that in the living room (just sheers) but in the bedrooms we may need to place furniture under the windows, in which case shorter curtains would make sense, but may look odd? hamamalis, we just replaced these windows with dual pane low e in the same size (after photos taken). The living room windows face the street this is a city house so no sweeping views here! Reframing walls is very expensive here due to labor costs so enlarging the windows didn't seem worth it. I would have added a window to the right of the fireplace to balance things, but the cost was high. We have a large glass wall and patio slider in the dining area which leads to our side yard, so that's our best view/ outdoor interaction. Eventually we may add a French door to the backyard at the end of the hallway which currently terminates in a linen closet - for more light and connection with the backyard.

You need height and window exposure. Swap the black curtain rod for one that matches your faucet or a bronze to coordinate with your cabinets, so the contrast is not so extreme - you don't want to emphasize the horizontal lines. Put your drapery rod on the wall above the window trim, not on it, placing it just low enough that you can either use grommet-top curtains or hang the curtains from the backs rather than tops so they will be higher (and longer overall); this will also hide the horizontal pole when they are closed. If you go with hang clips, be sure to gather the fabric adequately (you might need to buy 2 panels for each side and stitch them together); it looks like you did not fold the fabric when you attached the clips to your curtains - so they sag. Make the rod wide enough that the curtains can be pulled completely to the side, revealing every bit of glass (garden view and natural light). Hang poles - the type used for vertical blinds- , one on each of the center rings, so you can easily open and close the curtains; these might also add a needed vertical detail. Do NOT use horizontal striping in the curtains - nor oversized swirls. Consider a toile, soft floral or a leafy vine (vertical) pattern. You might find something at Vermont Country Store, if you are having no luck at the bigger retailers. .
