Thanks for the link Will. Obviously Cyberian's GUI has more switches supported.
The GUI I posted, was born after a suggestion from daMANiack to create one.
This is just version 0.2 for the GUI and I have included only the most used switches.
To be honest, I wasn't aware of Cyberian's GUI when I started developing one for daMANiack and for personal use. It helped me to add some unique features to this GUI. I was mainly concerned about making a GUI which was fool proof and minimizing the chance of making errors while creating the image.
I was planning to included all the switches as I get more time.
Edited the initial post to add the change log.
Cheers,
