New in Excel 2007, you can now make the formula bar higher.
Between the column letters and the formula bar there is a line. If you point to the line Excel displays a double-headed arrow. You can click, hold and drag the line down to expand the Formula Bar.
This is extremely useful to display long formula without the formula covering the spreadsheet entries.
