This is a feature I previously had in ProductPlan, and I miss it horribly. Dates for releases, epics, initiatives are constantly in fluctuation, and currently there is no way to auto-adjust or even manually adjust the date ranges when a team gets stalled, for example. It is very time consuming to go into each object to change dates.
I too used to use it in ProductPlan
Very mucn would like to edit start and end dates of capabilities by dragging directly ona custom roadmap!!!!!!!!
Thank you for reaching out. It may be helpful for you to use the [Shift] key to select multiple items in the timeline. Then you can click and drag to adjust all of the end dates at once.
