What does the plugin do?

Hi, I was looking for plugin which could add a hover effect, to the WooCommerce product images in the store or category grid listing. Just a simple highlight or greyscale would be adequate.
Does your plugin do this?
I don’t want the other tools such as heading colour editing or layout in grid (there are plenty of fully featured plugins which do those tasks).
Can you update your plugin’s ‘demo’ page to show what it does please?
