Would be great if we had the option to take a saved filtered view from the 'Release>Portfolio' screen (therefore if you have created a view where only 3 of 7 active releases are visible) so that when you go to the 'Feature>Board' view only those 3 of 7 active releases are displayed, almost like a synch option. The feature board is the most common feature listing view and seeing all releases when we really only want to see specific ones that are in synch with the Release>Portfolio view would be ideal (rather than moving releases in/out of parking lot).
Since this idea was originally submitted we have added a Release filter to the features board. It is now possible to select which releases to show on the features board using this new filter.
Given this capability, it is unlikely that we will add the automatic sync with the releases shown on the portfolio roadmap or gantt chart.
