Don't know whether this is the right place to post it.
i've created a mel script for controlling the default shader (lambert1) transparency. I find it useful while modelling using image planes. u can see the image planes by adjusting the transparency.
i posted it here 'coz it's still in progress.
I need someone to help me in scripting as i'm new to MEL. How can i close the window when the user creates a new scene or opens another scene

chk the file
