Tried this on my nexus 5 and when I press the power button to lock my screen it flashes up the original lockscreen (with pattern) and then it's replaced with the one for slidelock.
Some suggestions for future releases.
1) Add the ability once you have swiped to show the lockscreen pattern (looks nicer)
2) Add the ability to use it as a complete lockscreen replacement to stop what is seen when turning off the display (see above)
3) And last of all breathing notifications, quiet times for when you do not want the screen to wake up.
