I've used Neo Launcher ever since that Nova crap came about, and actually had to just double check I was using Neo still since it just.....works as my Launcher?
Which brings me onto another point which always made me curious people who used to say that using Live Wallpapers saying it decimates your battery life and well, it probably would if you spent all day looking at it, but then I got thinking how much time do I spend looking at my home/Launcher screen :thinkyface:
Lawnchair has an open alpha on their telegram. Try that if interested. Besides that, try the suggestions in other comments. Personally using smart launcher. Could give it a try.
I don't have an answer, but I have a suggestion. It might help describing what lawnchair is, what you use it for, or even provide a link to the documentation. It's entirely possible people are using something similar or better and have never heard of lawnchair.
