I like this launcher a lot. Unfortunately, I've got the same screen glitch as reported by @Chris95X8. It usually appear after a few mis-swipe due to my thumb touching the far left edge of the screen accidentally.
In the notification centre, the Glovebox item says "Press to restart;". However, there's no feedback on whether the "restart" has taken place or not.
Also, not a big fan of the Glovebox slide transition effect, it seems to lag more than the stock Jelly Bean app switching / launching animation.
