Metalloids can be defined to include any arbitrary set of elements. This set can be stored as the startup default. Extensive editing is available for periodic tables. Two properties and the element's symbol can be printed in the cell. The variable-color display can be rendered as grayscale.
Columns can appear to lean in any direction.
Window colors can be set. Separate font and cell colors can be set for cells that are selected and for which the database has no value of the display property. The position of all text, the dimensions of the legend, the placement of the title and the margins can be set. The number of decimal places for display of properties can be set independently for the top and bottom properties. Metalloids and inner transition elements can be defined separately for individual tables.
