The formula editor allows you to create and modify your own formulas. These are specific to your account, although you can share your formulas with other users. These formulas will each have their own icons, and can be used just like the built in formulas. The formula editor offers some data which is not available as predefined formula. However, the real power of the formula editor is that it allows you to mix and match the various data items in an almost unlimited number of ways.
