Sliding panels perhaps.

Some kind of blind (Hunter Douglas Silhouette blind, for example), that rolls up and virtually disappears.

No way to have panels unless they all stack to the right if having window completly open. What space is this as all I see is outdoor furniture, is it a sun room?

I'm getting light filtering roller shades with a cornice to hide roller on my new 8' slider. That way we can adjust for TV viewing as it is in our FR. I had verticals on old slier for 20 years and wanted a new look.
