awesome Waardering 4 van 5 sterren
One of those few extensions you install and just say, "wow". Might not always be necessary but when it is it's a simple and useful idea. I concur with some of the other reviewers that it would be nice to have the cloud in the empty space on the right side instead of on top.
Also, the donate/review/share link that shows above the cloud is creative, but users aren't going to want to see that forever.
