Fast perfekt! Manchmal wird eine Seite nicht gefunden, andere Seiten sehen seltsam aus (Querbalken), manche Sonderzeichen (Formeln) funktionieren (noch?) nicht ... aber das wird hoffentlich noch :-)

Evet

I don't know much about the technical pros or cons of this extension but the look and feel are great. Really well done, also the pop-up windows which show a summery info of highlighted words found in the text makes researching so much more enjoyable.

Loving the re-designed Wikipedia; the old design just looks outdated and cluttered.
The table of contents looks amazing too, and it's very handy to be able to access it from anywhere in the page.
Perhaps there can be some customizations for the link preview, such as box and thumbnail size or transparency.
Other than that, many thanks for finally get rid of the "Install Wikiwand" button.
