Is there a reason "showing" is private in NGUI scripts?

[Jaroe]

For my project, I have gotten rid of the mouse cursor on-screen unless one of the interface panels such as the inventory or character panels are opened. (Actually, I turned it into a reticle in my latest rebuild of the code.) But in order for this to work, I need to edit files such as "UGUICharacterPanel.cs" and modify "bool showing = false;" to be "public bool showing = false;" This allows me to call them from the "Atavism3rdPersonInput.cs" script to see what windows, if any, are opened and therefore stop the camera and player from moving. So far, what I've done works great and I only have to go back to the scripts if one of them are changed in an update. I just want to be sure I won't be setting myself up for other problems in the future. 

It might be helpful to note that I also allowed the mouse to rotate the player without pressing either of the buttons. 

Further note: I've created two public Boolean values in "Atavism3rdPersonInput.cs" that can be checked before or during runtime to revert back to the default mouse cursor and controls.
