The Explorer generates thumbnails for multiple worlds, any of which can be either transferred to the main World View page, or which can be used as starting points for searching through a series of worlds.
There are two different Explorer modes: Random Explorer and Series Explorer. The Random Explorer generates a set of completely random world maps. The Series Explore generates a set of more or less closely related world maps.
To transfer a thumbnail to the World View page, click on it to select it, then click the Copy to World button underneath the Explorer display. Alternatively, simply double-click the thumbnail.
To transfer world details to the Series Explorer, click on it to select it, then click the Copy to Series button underneath the Explorer display.
