Plugin Compatibility Question

Congrats on the popular plugin! I offer a plugin that sends out notifications when something a customer wants is back in stock. Problem I have run into is that there are many people who use your plugin for managing their stock, so these alerts do not work. Do you have, or would you be willing to consider adding, action hooks where the stock values are updated? Ideally I would just need one hook that sends the product ID, the previous stock, and the new stock. My plugin would then compare the numbers and trigger an alert if necessary.

I appreciate your time and consideration, thank you!
