Just to clarify the significance of the photo: the body of water in it is Neitokainen: https://en.wikipedia.org/wiki/Neitokainen

It is a lake in Finland that has the shape of Finland.

The scale of the image, which makes it impossible to fit in one screen, makes this hard to spot if one's not intimately familiar with Finland's geography.

The lake itself is also interesting, but the fact that it was artifically shaped like this, makes it a little bit less interesting.

Also, in addition to showing the creation date of the API key, I find it super friendly if it is possible to name the API key (and/or add a note to it).
