In working with the Program Roadmap, my teams have expressed interest in having the ability to zoom out / in on the timescale.  Several have noted that when looking out up to 2 or 3 years into the future, the width of the month bars is too wide and would like to be able to zoom out from the current Months view to Quarters (with the corresponding months) or Years (with the corresponding quarters).  In this case, the Quarter or Year would have the same width as the current Month display would.  This would improve usability of the Program Roadmap.  When the Solution and Portfolio Roadmaps are released, this would also be helpful on those Roadmaps as well.
