Appoggiatura display in piano editor too short

See graphic of PRE (piano r ed) display and score measure at its right. With the PRE, it is easy, well, it's possible, to accurately length-adjust appoggiature to desired durations (the "1/2 main note" is sometimes right and sometimes wrong). Here, I want an eighth-note ("125" out of the main-note 1000). I cut back the start of the main note to 125, from 500, and the end of the appoggiatura the same 125. Sounds perfect! The display of the appoggiatura in the PRE is wrong, though. It should clearly cover the full space over which it sounds. But this is a great boon in any case!
