Froyd villainrom is a great rom. But if you don’t like the lights (the led blinking, the trackball light) you can replace the lights.hero.so file under the path /system/lib/hw/ with the file from older versions. If you don’t have one, you can download from here.
You can do following steps in console to replace a file under /system/ folder if you have adb tools:
adb remount adb pull /system/lib/hw/lights.hero.so ./lights.hero.so.bk adb push ./lights.hero.so /system/lib/hw/
