Toolbar item	Icon	Description
Clean and Arrange in 2D		Cleans structures and positions them to the center of the canvas.
Clean 2D		Calculates new 2D coordinates for the molecule.
Clean 3D		Calculates new 3D coordinates for the molecule. Clean3D builds up conformers of fragments from which the best, that is, the lowest energy conformer is given back. The quality of the structures is measured by a simple energy function (Dreiding-type molecular mechanics).
Convert to Aromatic Form		Transforms the molecule to aromatic representation using the transformation method set.
Convert to Kekulé Form		Transforms the molecule to non-aromatic representation.
