The Explorer toolbar appears directly underneath the main Explorer display, and provides quick access to most of the Explorer functions.
Start / Stop
The Start button starts the Explorer producing thumbnail worlds. As soon as it is clicked it changes to a Stop button (both the icon and the caption change), which can be used to stop the Explorer if you want to cancel it before it has finished generating the current set of worlds.
The 'Clear existing worlds' checkbox immediately above this button determines whether or not the Explorer will delete existing thumbnails before generating a new set.
Deletes all the existing thumbnails.
Copy to World
Copies the currently selected world to the World View and re-generates the map at the selected image size. World Builder will automatically switch to the World View page when you click this button.
Copy to Series
Copies the current world to the From edit box of the Series section in the Options panel, and sets up the To and Step values to generate a suitable sequence of worlds.
