In Excel (and inside cells in MV), you can type Alt+Enter in between parts of a function to separate the text into multiple lines (fyi - it may cause some unwanted formatting changes).  I'd love to see this function, or some other way to use "Enter" inside the "Edit Formula" box to help formulas be easier to read and interpret. 

That is where we do most of our formatting, and it would be really helpful to have a way to organize formulas inside it.  We use spaces as a work-around, but now that the window changes size (and opens at the previous size) spaces create unpredictable formatting results, so they aren't as nice as having the ability to "Enter" would be!
