Opting for the wardrobe slide meant sacrificing an opening window in the bedroom. Problem solved by replacing the door window with one that opens. Looks better than original, too.
Here it is from the inside. Look upper left and you can see the catch that holds the window securely up.
View from inside. Door screen doubles as window screen.
I also added Plexiglass panels to the living room screen door to convert it temporarily to a storm door. The panels fit into an existing groove in the door's frame. Upper and lower large panels are held in by screen spline. The smaller panels in the center of the door are press-fitted and will remain permanently.
My cheap-***** point-and-shoot camera couldn't get the close up detail well.
Here is the door.
Here's a pic of the upper radius with the spline exposed.
It's hard to see, but here's a shot of the lower section showing the position of the glass with a tag end of spline showing.
If you look at your screen door, all this will become obvious.
