There are six column headers you may change at the moment. If we take a look at our public roadmap, we can see the six labels.

The top three tabs are by default Roadmap, Launched, and Ideas. The Ideas tab is optional and can be enabled from the roadmap settings.

The three columns of the roadmap are by default In Progress, Soon, and Future.

You may customize the labels for those columns in your roadmap settings. Only change what you need and save.

The changes will affect your public facing roadmap as well as some in-app key parts.
