One of the nice new features in Winter'18 is the ability to wrap/clip text in a list view (and to resize columns, although this is already there in Summer'17). For some reason this resize and wrap/clip functionality is not also available on the Reports or Dashboards tabs in Lightning, which is quite annoying as some of our report & dashboard names are quite long, and get truncated for users who are working on older, square-shaped monitors. They have to hover the mouse over the report/dashboard name to see the full title in a pop-up.

 @Michael Orr I know it's a small thing, but can you please add this to your roadmap for the next release? I've logged an idea for this: https://success.salesforce.com/ideaView?id=0873A0000003UjvQAE
