I'd like to be able to visually show the status of my releases and features on the gantt chart view.
We're in the midst of actively grooming our Idea backlog. We had shipped a feature related to this on the Releases roadmap screen where you can Color bars by status.
This will use your specific feature status colors. You also have the option to configure the colors used for each status by going to Settings->Account->Configure status, workflows, and feature types and selecting/editing the specific flow for your product.
You won't be notified about changes to this idea.
