I have been working on our Workspace, looking to add some of the default rollups. After adding them, we noticed that there was a lot of excess space that was being wasted by default due to the length of the names of the Rollups, including out-of-the-box ones (Number of Completed Activities is one we want to add). It seems a waste of space and time to make a duplicate rollup with a shorter name instead of allowing word wrap on some fixed pixel length. However, this is currently not possible.
