We are regularly being requested by our clients can we see the dates and assigned too/tasks in the Gantt view via: Releases>Roadmap. Because we can't show the dates (we can show the letter of the day and the week start date), they then ask us to re-produce the gantt view in other tools such as Smartsheets or MS Project. If you could have dates visible at the phase level next to each phase that would be ideal.
As described in the comments below, these types of views can be created through the Reports->Timeline page. The Pivot view also has additional capabilities which can support a visualization which supports dates on releases.
At this time, we do not have plans to make changes on the Releases Roadmap page but we hope that you can achieve the same goal through the Reports page.
