If there is enough room on or around the casing Area of wood, you may choose to use a Duette® or soft shade that has a very small headrail system and stack is a possibility. When the door is used, the treatment can be drawn up tightly and not be damaged easily by the wind or caught up in the door. I also like your idea of a drapery on a wood pole and wood rings. When mounted outside the window frame, however, it would hide the wood trim along the top of the window. This could be a drawback. I would choose an Area about halfway between the bottom of the arched window and the top of the slider window and mount the pole on the open Area of the wall. Also, use a one-way panel. Depending on the color of the walls, I would choose a fabric that would blend with the wall, which will in turn blend with the existing wood blinds on the other windows.

Another suggestion would be to use wood blinds. Mount two under one headrail. This would keep continuity with the existing wood blinds.

Also consider sliding shutters with two-inch slats to match the wood blinds. The panels are installed, one stationary and the other sliding depending on which side of the door opens. Vertical blinds may be a possibility, depending on the style of the room. A color to blend with the wood blinds and furnishings would make a nice, versatile treatment.
