The left columns (group bars by fields) in the custom roadmap work and look identical to pivot reports. In pivot reports, the wrap text view option allows resizing of those columns, but this is not an option for roadmaps.
It would be useful because for roadmaps, minimizing space on the left to maximize space on the right is critical.
yeah, we would value this for the other reason: if I have a 'Group By' section that is longer (and thus takes up a lot of vertical space), I would like to be able to adjust the width to be wider (so more of the rows are visible onscreen at once).
