The add-in Adequate contains a ZoomEditor.
This comes in handy when editing large formulas.
The font size is adaptable, as well as the editor’s transparency.
You can also use a function wizard.
Another clever tool is the SpaceOnizer, which automatically places spaces around the different parts of the formula, upping the readability.
