I have grub customizer installed on LL 3.0, I've used it for the last few versions of LL. However, I installed it Via terminal. You might want to give that a try, worked for me.
sudo add-apt-repository ppa:danielrichter2007/grub-customizer
sudo apt-get update
sudo apt-get install grub-customizer
If you're worried about having another addition your your repository you can always delete that after installation. Just go:
Menu > System > Install/remove software > Settings > Repository > Other software (tab) > Untick the 'grub customizer' box & close
