Technofreak: I'm not sure which screen you are referring to but you can put anything you like on the unlock sceeen.
The N9 is probably the easiest phone to close apps on. Just swipe down from the top of the screen - app closed.
Have you had time to look at the onboard user guide?
Set up Swype as your keyboard, it takes some getting used to but very good once you master it.
Meego is very different from S6 V5
Some of the features of the N9 are not immediately obvious. Stick with it you'll I'm sure you'll become a fan.
I am slowly figuting it out, when i double click it/unlock it I see the wall paper but when I return from apps its a black screen with the weather and date. and time.. Dinosaur I know,
