If you look at the plato and koreader shell files in the .adds/nm directory, you'll notice they have two methods in each of launching the app.
Plato:
Code:
# Launch Plato via KFMon
# NOTE: .adds/nm/kfmon will generate this automatically
#menu_item : main : Plato : kfmon : plato.png
# Launch Plato directly via NM
#menu_item : main : Plato : cmd_spawn : quiet : exec /mnt/onboard/.adds/plato/plato.sh
