If there is no need for privacy, I'd have the 2 curtains as you had (or no curtains). Sometimes curtains on the end like you have look cute tied back a bit and facing one another:

If there is no need for privacy you don't have an issue. On the other hand if you want to dress up the area it would be nice to have side panels on each side of the side window with one continuous rod across all of the windows it would look more finished. It is up to you whether to have enough fullness for functional drapes so you could pull them across to cover all the windows or just want decorative side panels.

If there is a need for privacy you could add a center rod over doors, take off the finials on side rods and line all three up. Treat the windows as a bay window and hang panels as you would a bay. For my slider I added a double rod with sheers behind that I close every night.

If you want privacy, it may be a better idea if you dress all the three windows with drapes and consider them as one bay window to create a more tidy and clean look.

Thank you all for the suggestions! We don't have a need for privacy since our backyard is woods. It would be for only decorative purposes. In you opinions, should I leave it as is or would it look better to add some dummy panels to make the area look more finished? Thanks!

I think I would remove the shades and the curtain rods, but then I'd have to repaint walls or touch-up.

Then again, maybe I'd add curtain panels. I am only seeing a small part of the kitchen. I do not live there. I have no idea of how this nook area works nor its relation to the kitchen or other rooms and the outside wooded area.

The important thing is to inject yourself & family into the kitchen. Some might want a valence or curtains. Some might stencil over the slider. Some might hang stained glass trinkets on the windows. Some might add many bird feeders outside...

I would do dummy panels just because they add so much and do give the finished look. If you don't like them, you can always take them down and use in another room.
