This string is just a placeholder, right? Will you please add a TODO to update
these strings or remove this file (whatever the next step is).

[Finnur, 2017/03/27 16:50:41]

Not really a placeholder. I used another string to get around a lint error
somewhere, as I didn't think of @null. Meant to get back to it, but forgot.

[Theresa, 2017/03/21 15:36:59]

Is this for the selected background? If so, selected_bg or selected_background
would be a good id, and the content description can be @null.

[Finnur, 2017/03/27 16:50:41]

Done.
