Two palettes are available to the Rich UI editor. Each provides the same widgets as the other, and in each case you can right-click the palette or one of its drawers to display a menu that provides Eclipse-based options.
The default palette is tied to the Rich UI editor. You can resize the width of the palette or dock it on the left or right.
The effect of selecting the Palette view is to close the Rich UI editor palette. If you want to return to the Rich UI editor palette, close the Palette view.
