As an integrator I can get preprocess visual edit changes

[djay]

e.g. instead of the value change going direct into a block state or metadata state I can register a callback to recieve the value. then I can call an api on the bridge to set the change I want.

Useful for?

• good example might be teaser. if overwrite is false but you want to make it so that you can edit it first and that will turn on overwrite automatically?
• maybe to edit parts of the page that get stored in special apis? like edit titles?
