Why exactly did this deserve a seperate post instead of a reply on your previous post?

The difference between +l and +L is whether they show on the taskbar. In order for something to appear on the taskbar it must be a desktop window.

/window -d +l @test
/window -d +L @test2
Note how @test is on the taskbar and @test2 is not.

The n/x flags only have meaning when used with the t flag (a maximize/minimize button isn't displayed if a titlebar isn't displayed)
/window +tn @test
/window +t @test2
/window +tx @test3

And I could go through all the others but I hope you can figure them out now?
