Windows with On/Off Curtains & glass

It would be awesome if the windows had the option to “turn on” or “turn off” glass…currently, some windows have glass, some don’t…but to maximize customization, being able to make any window have glass or not would be great. Likewise, being able to click another button on a window to have a curtain/drape suddenly cover it would be amazing, with maybe another button to select patterns, colors, etc. A glass selector would also be fun…clear glass, frosted glass, dirty glass that you can’t see through, etc.
