The Themes dialog
A render theme decides how an offline map is drawn.
What a theme is
A render theme controls which map features appear, in which colours, and at which zoom levels. It changes the drawing only, never the map data itself.
The two lists
The dialog shows My Themes: (available now) and Themes available for download:. A theme can be applied to any offline map.
Apply a theme
Select a theme under My Themes: and press Apply. The map redraws immediately with the new theme.
Download a theme
Select a theme under Themes available for download: and press Download. Progress appears in Downloads.
Pick a variant
A theme may offer several styles (variants of the same theme). To choose a style or toggle feature categories on or off, see Theme styles.
