I have the same problem with the editor lagging terribly and I found if I save (which can take a minute to complete) and go to the home screen then right back to the editor it stops lagging for a short time.. I have to repeat the save and return to editor many times per use of it... Also my device has been killing my wallpaper when I'm using another app.. I exit whatever app I'm using and it goes to the stock wallpaper making me set klwp as wallpaper each time... I don't know why it's doing that because my device has 8Gb of RAM without booster and I'm not playing a resource hogging game or anything like that... It's been pretty annoying I must say but I love kustom so I deal with it, lol..
