I would like to choose black window and green font.
Err... I think that would make some of the script's functioning diffictult to handle. For example, normal text is black, because commented text is green, and numbers and messages are red, and int, short, string, etc are blue.
If you were to be able to change everything to green, it would make reading the script very difficult.
Some sort of script editor customization is a possibility, but to be honest it's quite a bit of work for something that isn't really very important, and for the time it would take there are other much more useful features that could be added instead.
