The page 'general' was the first place I looked when I
wanted to change the theme. Not managing to find it,
I went on a search throughout various issues ( #46 , for

Now I hope to spare others the search
* Hint the user about themes
When I was on this page, it wasn't immediately apparent
to me that the SettingsListItem was clickable (I thought it
was a list rather than a button)
