When I switched over to Lollipop on my Nexus 5, I was too lazy to transition back to the Google Now launcher to get that Lollipop aesthetic. Instead, I stuck with Nova, knowing that eventually I'd get the look on TeslaCoil's third-party launcher. Well, today's the day, assuming you're running the beta version of the app.
It's a pretty simple tweak - just jump into Nova's options, head into the Drawer section, and tick the "show pages as cards" button. Done and done.
Other than that, the changes are few. Here's the full log:
3.3beta1 Nov 19, 2014
-Lollipop style drawer (Settings - Drawer - Show Pages as Cards)
-Renamed old Circle animation to Circle Wipe, added Lollipop style Circle animation (requires Pages as Cards)
-Fixes and optimizations
And that's pretty much it. The update should already be live in the Play Store, so jump in and grab it.
Note: You must first join the beta community if you haven't already.
