Time for part 2 of how you could manage your UI windows in Unity 5.3! Part 1 brought up some questions that I like to deal with first. Things like having only one root canvas for all windows, preloading windows to not have a lag when opening one and animations when opening/closing a window.

UI Window Management in Unity (Part 1)
If your game contains at least some user interfaces, you will quickly run into the need of manage them in a central place. In our past games we developed a generic window manager that can be used in any project. It takes over the all the loading/unloading of windows and makes sure windows are not opened multiple times.
