Actually, I'm pretty sure you could, just mess with the code a bit.this is right but it needs a really good java programmer to do that .
Edit : sorry guyz , I change my post . I'm java programmer , after checking the code it's obfuscated . I thought it's open source program and all files are there but I was wrong . All u can do is just wait until selpjohan make us a new one or make one to urself
