I'm going to suggest that we further simplify the design of the login page as there are a number of UI features which belong in the previous century, and the design is still slightly too cluttered.

In short, I'm going to suggest that we should consider some more drastic changes:

1. Remove the Footer entirely - especially when it is empty, but also consider hiding the performance info (collapse it perhaps) when stats are shown
2. Make the login region wider. For some reason it appears narrower now than it does on the screenshots from when Angelia tested MDL-69371 - considerably narrower.
3. Remove the Cookies warning - we should only show information about this when a login fails because cookies are not enabled. It's a standard feature of browsers and very very few people disable cookies. Logins are too prevalent these days to consider disabling them entirely.
4. Reword the "Forgotten your username or password?" link to simply "Forgot password?"
5. Remove the "Remember username" checkbox entirely. This should be the default. I quite like what Chrome have done whereby they show information on how to open a private browsing window if you do not want your login to be remembered. This is a much safer and more user-friendly approach.
6. Make the username and password fields taller. At the moment they're really short but they are the main focus of this page. We should make the area that users are expected to interact with more prominent. Equally we can increase the padding around them to make the area clearer.
7. Move the Language selection to beneath the username and password fields. The Username field should be the first field in the tab order
8. The "Username / email" placeholder text should read "Username or email" rather than having a slash (not very user friendly)
9. I'd like to suggest that we move the Cookie warning, to a new page which opens in a popup. It can also have the information on starting a private browsing session, and any other help we need to show in future (i.e. password recovery for admin, etc.).

Comparing a number of other big login screens, none of them has the "Remember" or Cookie warnings.
