Docker's interfaces provide a fun (not) and interesting (not) challenge. It's called "Spot the links".
The logo is a link. The tabs are links. Top-level menu items are links. The "Edit profile" link is a link. Even the buttons ("Create Repository +", "+" and "Explore") are links.
What boggles my mind is that it's actually harder to implement this mess than to let links be, well, links.
