It would be very useful to be able to add Jira Cloud fields as a column in list view. The obvious example would be the Jira Issue Key, but the ability to add other fields would be ideal (e.g. Summary, Priority, Type, etc.).
One of the benefits of this would be the ability to quickly see which tasks have linked Jira issues, but also allow linked data to be visually scanned quickly (rather than having to select each task in turn).
(I notice someone else raised this some time ago: Have Jira Cloud issue link as a custom field).
