Some formulas in Coda can become complex. As they become more complex they become less readable. I would like to see the ability to format formulas using line breaks, comments and tabs to increase readability. This is particularly important when trying to maintain someone formulas written by others.
Additionally formulas should be created and edited in a much more functional window that allows resizing.
Lastly formulas should be able to be locked or owned by the author so they are not inadvertently changed.
