It would be nice to be able to have a wraparound for the tool names when they're in the shelf. Most people are not going to have an intuitive PNG handy, and sometimes, it would be easier just to have an option to give a descriptive name that can be expressed in more than just 7-8 characters so you don't have to hover over each one and pray the person who wrote it (including yourself) included a tool tip over a tool you don't recognize (anymore)
