This is a fairly basic spreadsheet program, designed more for the average user than for doing extensive calculations, although nothing necessarily precludes heavy use.
It supports nearly all of the features I have personally used including cutting & pasting, insertion & deletion of rows and columns, a customizable appearace, basic graphing, and it uses fairly standard parsing of formulas including recognition of ranges of cells and several formulas.
This program offers you medical information and human body illustrations.
