well..i do have an idea about how Grid Creator could work (improve)....
 the user could just open his favorite applications, and arrange them as he would like on the desktop... and then when u ran Grid Creator, it could automatically create the grid that the open application are creating. For example... I need on my screen opera, a chat windows, and 2 web cam windows.....i just arrange them the way i would like the grid to be created and I just run grid creator and I'm done.
