TL Thank you page Upsell

Terrific app for our use case: we need to add a button to the thank you page to take users to our app if they bought specific products.

I've suggested a couple of enhancements that would make it even MORE perfect for us. They've already implemented one of them (adding an attribute to the forwarding URL of the button.) I'm hoping they'll be able to do another related to button color.

Outstanding Customer Support as well.
