Initiative Burndown Charts Merged

It's very frustrating that I can only show a burndown chart of one release at a time. We want to see progress towards initiatives so we can judge our progress towards completion of those. We have found the burndown / up etc charting in Aha very disappointing so far.

This idea would only require using the exact same view currently shown for Release progress / burndown, but instead of showing points and features attached to a release, show any features that are tied to a given initiative.

While we're talking about it, "view progress" is a strange way to hide a burndown chart. It's not obvious to many of us.

(In the future, of course it would be great if there were also other options for burndown charts so I could show any set of features and filter them arbitrarily just like in the features board -- but that's not part of this specific idea.)
