// TODO: 
// * Dump the refs into a list, where clicking each opens a textarea with its removed ref data.
// * Timer to check for new number-refs, add them to list, allow creation. Check duplicates [12][12], highlight removed for re-insertion.
// * Handle slashes in: ref name="aa/bb".
// * Entry form for template refs instead of textarea, make ref list look nicer.
// * More efficient, if problems arise.

// "...that removes all refs into an a div below the edit textarea, replacing them with numbers[439]. 
// If you mess with the number, the ref-down-there turns red. Click the button to inject another ref 
// below using reftools, and a number inline. Parsing/replacing the refs wouldn't be very difficult, 
// and then add a timer that makes sure the numbers are all still there in the text. Offer little 'add 
// this ref' for any new numbers (so right now I'd see '439: [click to add ref]' somewhere below)."
