Would it be posible to modify those little apps, so that when we launch them, no picture/anything is displayed and the "focus" remains in the current "windows"(:P) ?

for example, if we are on springboard, we stay there, and the app does its stuff "in background"

furthermore, if the previous thing was posible, would it be posible to launch them from dock from whithin an app, and stay inside the app ?

thx
