Currently, the features added into the Starter Roadmap are a month long. When working with smaller timescales, this becomes cumbersome. Having the ability to set a new default duration would save a lot of clicking and resizing.
Thank you for your idea. We have recently updated the default feature length for features added using the starter roadmaps to be 7 days. Hopefully this has improved the experience when working with smaller timescales.
We are unlikely to make this a configuration setting, but we will continue to monitor customer feedback.
