For why these are superior:

Fully open mode = big hole for air go thru.

Slanty mode = very windy ez, rainy ez, rainy and very windy... just close window.

But, the innovation I miss more than the windows were the roller shutters.

First of all, light blocking. Forget blackout curtains or something, just roll down the shutters and no light is getting in. If you work nights or something, you can block the sun completely and sleep in the dark. Along with that, the light is being blocked while it's still outside. Why does that matter? Light means heat. In summer you don't want the heat inside. Block it at the shutter and it doesn't come inside to heat the inside of the house. Compare that with blinds, curtains, etc. In that case, the light has already entered the house before it hits something and heats it up. With white curtains you'll reflect a lot of the light back out, but you're still heating the interior of the house. They also reduce noise, add security, protect in bad storms, etc. But, to me, blocking the light and keeping the heat out was so much more important.
