Timeline is currently not a supported column for the Item Card view widget. This would be a great added feature for our organization.
Use Case: We currently have 51 projects that we are tracking through our project processes. Each month we have a meeting to give a general overview of each of the projects. The itemcard view or widget is super helpful for creating a visual status report of each project as we review, but it lacks the ability to see or adjust the timeline from this view, which causes extra work after the meeting for the project manager to go in and change it, if it gets updated at all. It is easy to forget to discuss the timeline, when it is not seen during the project meeting.
