I agree with most of the features, with an emphasis on the indicator icon. I would also like for the indicator icon to be available in the gui mode; unlike ccleaner, defrag can take hours to run, and I don't appreciate it taking up space on my status bar. I'm not going to click over to it. If it shows progress, even better--especially if you can make the tray icon a mini progress bar. For example, zonealarm shows internet activity as a red and green bar, other programs show a blinking icon to ask for attention.
