Re: How to organize many icons?
Your programs can be accessed through the Dash (right-click the Ubuntu icon and choose Applications). Rather than litter your desktop with everything, just access your less used programs from the Dash and your most used from the Launcher.
I try to treat the cause, not the symptom. I avoid the terminal in instructions, unless it's easier or necessary. My instructions will work within the Ubuntu system, instead of breaking or subverting it. Those are the three guarantees to the helpee.
