+1 I completely agree with you! The current version of DiskUsage, is totally unintuitive. Many times I tried to use this program, but I could not understand it. Nice mockup, but the tab is not needed for a single view, or two. I get a feeling of empty space. Unless you add more options? Maybe SMART reading, some benchmarks, seeking bad sectors, checkfs, defragmentation( btw never defragment an SSD - http://www.micro-isv.asia/2010/12/never-defragment-an-ssd/)? Then you would have to change the name of the program ;) - DiskDoctor :P.
