Little control over the element: UPDATED REVIEW
This is a brute force solution to make an element's opacity pulse from 0 to 100. I can hide it on page load and trigger it from a click. But I can't hide it afterwards. Once it starts, there's no stopping it. UPDATE: Version 1.7 added a toggle to turn start and stop the pulse. It's not a proper on and off command. I was still able to use the plugin now that I'm able to toggle it. But It would be nice to be able to have the start and stop actions be separate actions.
