Aborting NSISW

It would be nice if you could abort a long compile if in the middle you remembered you forgot something and want to abort

Its possible to add I guess. Although, I'm not sure its necessary. I could possibly change the ok button to a cancel button during the compile. I believe I had this in there at one point and removed it. I can't remember why though.
