I know... just like London buses - nothing for ages then two releases come along in quick succession.
But thanks to a good pull request that lets the ui_form node accept data to pre-fill it here we are...
Plus a small fix that got broken in the justgage update ...
- Let ui_form node accept input to be prefilled, and add multiline text
- Let dialog be removed by blank message.
- Fix undocumented change to justgage custom sectors api. Issue #547
