Many fixes & stuff im sorry

First off, im very sorry for my lack of support and updates as of late, I am very stressed moving into my final years of high school and also keeping up with work. I hope you can understand. I understand lots of people have moved on from this plugin, but I hope I can slowly regain your trust :)
