Nova & KLWP, any success?

Hey all. Attempting to use the Nova Launcher and KLWP, however, I'm having some issues with even getting it running.

KLWP won't even set as the background properly. Additionally, the Nova Launcher is seemingly refusing to play nicely with the 1+13 OS. Mainly the lag when swapping apps.

Any success stories here, and how did you do it?
