Using milestones for feature boxed sprints
Problem to solve
Currently, you can set a milestone with a start and end date, and get functionality similar to managing a time-boxed sprint, along with a burndown chart.
I want to set a milestone with just a start date, and leave the end date blank. In doing so, I want a burn down chart from the start date to the present. This is because I may be running a completion boxed sprint/milestone rather than a time boxed one.
Essentially, I want to see a milestone burndown chart for the case where a milestone has a starting date, but no ending date, from start date to present. This seems actually like it should be a rather minor tweak to the existing burndown implementation in milestones.
Ideally, I would like a completion based milestone to also record its end date when it is closed.
