>
> Describe alternatives you've considered

> Additional context
> Add any other context or screenshots about the feature request here.

Start by tracing how the DMT front page renders project buttons and where project status data is available, then compare the requested behavior with the copied issue at equinor/dot-archive#28. Done means project buttons visibly indicate at least a completed status, with any additional statuses supported by the available data.
