The interface on my Blackberry Curve is extremely annoying. Each icon on the screen represents a function or  program. But to select the icon, I have to use the roller ball to scroll through all the icons (some which I'm still not sure of what they do). Sometimes the roller ball moves fast and misses the icon. To fix this, I would organize the icons by similarity and subject into folders. This would greatly de-clutter my screen and make it easier for me to find what I need.
