Feature request: Show dates in roadmap when relative dates are used

[m10herrero]

Good afternoon, Thank you for this great tool. I would like to request a new feature that I think may be very useful. When planning a project using relative durations for all the tasks I would like to see the actual start and end date in the Timeline. Maybe show the dates all the time or add a switch to choose either duration or start/end dates. Thank you very much. Best regards, Mónica
