This seems like a fairly obvious oversight with the column.search API.
Knowing:
- isHidden - boolean to indicate Active vs Archived
- isDefaultColumn - the one that Tasks get dropped in by default, usually called "Backlog"
- sequence - numerical order on the Workboard
are all necessary for a lot of things that very sensible real-world API clients need to do when working with columns.
Partial cherry-pick from:
