Good:
- Sidebar for navigation
Bad:
- Wasted screen space
- Other languages are not available as a simple anchor tag anymore. They are hidden behind elements. It's annoying for readers who consult their own language and en.wikipedia.org in the same session. It breaks my bookmarklet to change languages, which depended on something like `document.querySelectorAll('a')`
it does not only break your bookmarklet, but even vimium [1] is unable to focus the language selection. this is awful.
