With a selection tool in use and no artwork in the document (layers and
guides only), the bar shows Draw (Pencil), which switches to the Pencil
tool, and Place Image, which picks files for the Place dialog, as the
help page lists for a new document:

VectorCraft's own rules: the bar sits under the active artboard, or
under the canvas's center when the artboard is out of view, and leaves
out the Fill, Stroke, Recolor Artwork and Lock controls. Other tools, a
selection and a document with artwork keep their bars as before.
