Coda's original plug-in has been improved in some very important aspects:

• In general, the extensions will be more exact and better aligned between the various verses or systems.

• corrected extension length calculation (especially for left-aligned syllables)
• select how long to extend the line under and beyond the last note
• customizable offsets for continuation on subsequent staff systems and for the length at the end of a system
   

  Just get it right.
