Wake without unlocking

Just tried out the custom lock screen app. I think I'll get quite a bit of use out of it, assuming I'm able to get past this.

I use my power button to wake my nexus 6p, and view my lock screen, as a quick way to look at and manage notifications. With this app so far though, as soon as I press my power button, it just skips to my active app, no view of the lockscreen whatsoever. I want to make it require me to swipe or what have you.

Also does this app disable my built in pattern unlock?
