// CONTEXT DISPLAY: How would you prefer the list to behave when the term you're searching for is found in the title of a draft? If it would be useful to see the whole draft in this instance, set this variable to true. Otherwise, if you have lots of long drafts, you may wish to keep this set as false, in which case the first non-empty line of the draft is returned. No quotation marks required.
