Highlight changes right after leaving insert mode

It would be nice if evil-goggles can briefly highlight the changes that the previous insert-mode made, right after leaving insert-mode.

This seems like a nice addition at first hand. However, I did a quick a prototype and this feature introduces a lot of distraction.

I can share the prototype so you can try it yourself and let me know your opinion.
