I ran the program with default settings just to see what it was doing. No installer and nothing written to the registry, which I appreciate. However, I felt like Pitaschio tries to do too much. It completely rearranged my desktop and listed all my shortcuts (file/program/drive) at the top left corner. It doesn't coexist very well with Directory Opus either (double-click for a new lister, for example, didn't work). Also when you click to the top of the window in the blue area, the window just closes. I decided I needed more time than I have right now to play with the software and customize it to my taste.
