Suggestion / request. Well, two.

1. When you click "Go to full article" I think it should close the frame. I middle-click that link to open in a new tab, but the frame is still around when I don't want it to.

2. Similar, I think if I click the little icon and that frame is already open, it should close. This would make it act as a little pop-up preview, but if I didn't scroll around or anything, my mouse is still there.

Thanks for a good tool!
