Ability to show colour of to-do records on a whiteboard by status

Currently, to-do records that appear on a whiteboard cannot be coloured by status

It is hard to distinguish to-dos visually by their status in a whiteboard. Although you can adjust the card layout to show to-do status, it still requires reading the status to easily indicate the to-dos by their status.

1. Add to-do as a supported record as an Aha! shape

2. Allow whiteboard objects that are to-do records to be coloured by status
