‘Short Notes’ are a new feature you can use to enter short notes (up to 500 characters) on each horse and is a great of capturing post-race notes or observations on a per race basis.
They are displayed on the racecard/results view and on horse form, prior form and post form screens and you can edit them direct by clicking the field twice on the racecard/results screen or on the horse form screen but not on the prior form or post form screens.

Short notes can be exported by the exporter and they have been added to the system builder drill down preferences screen.
