Apex and Nova used to be fairly cloneish with almost exactly the same feature set. It is as pointed out already, abandoned. Nova is a good rec, also for something a little different you might try Action Launcher 3, it plays well with edge devices since it has pull outs from the side and you can still keep your edge pullouts. I used to use Nova but switched over to AL and after getting used to blinds and shutters I'm unable to go back. Not quite game changers but they greatly increase your options when you lay out screens. Combined with the scrolling bin and custom pull out page you've got something just a little bit more than your mothers launcher.
