Also, if there is a way to post screenshots to this forum, that would be super helpful?
You could always make a screenshot, put it on a image sharing site and link to it here. You can use HTML for this in your post.
<img src="yourlink.jpg" alt="">
I’ve been doing this myself, so when people click it they go to the image directly:
<a href="yourlink.jpg"><img src="yourlink.jpg" alt=""></a>
As to the first part of your question, that animation is all wrapped up in the main script here at the bottom. It’ll be difficult to extract anything from that and change the effect. I have not looked at the border issue yet.
