You can create a multiple line formula. Alt+Enter when editing the formula.

If I'm writing a longer formula that's going to be tough to read, I make it multiple lines and add spaces at the start of the lines for indentation. Makes readability so much better!

A good tip there for folks to help readibility. I also love to paste in really crazy formulas here to really see them in a well formatted mode in the cell.
