His first patch implemented only basic tab previews (as you may see in other browsers). But I thought we can do better! I told him, I want to make it really beautiful before merging it into repository.
So he started working again with animations in mind and my other needs.
Yesterday, he sent me his work. I really liked it, however I missed resizing and fade in/out animations. Today, I commit it into github.
You can see how it looks on this video:
Thanks again to Alexander Samilov and I hope you like it.
