I am sick and tired of finding out that I accidentally "nudged" an event opacity or volume level. Usually the amount is so slight, I don't notice it, but it forces re-rendering, and of course will cause unintentional degredation to the final result.

This script works best if you zoom all the way out so you can see the entire timeline.

/**

 * This script finds all events where the opacity level has been 

 * set to a level only slightly less than 100%, or the audio level

 * set to slightly less than 0dB. This usually is not intentional

 * and results from accidentally moving the opacity or volume 

 * line while moving an event. Without this script, such 

 * an accident is very difficult to detect, and can result in 

 * long rendering times.
