same rom update normally doesnt need to clean wipe, unless explicitly specified to do so

ask the developer yourself

I got use it but I feel quite buggy
I use the s4 launcher no magazine + s4 accuweather
everything work fine, but whenever I hide apps so that won't show in application drawer (because I already put them into home screen)
once I hide it, my homescreen that apps also hide it ==

example I put facebook app in homescreen, then I hide this apps so that it won't show in apps drawer
after hide it, homescreen that facebook app hide as well

store in sdcard or phone memory ?
and you backup using ?
right now I totally speechless of those s4 / note 3 / s5 weather widget
either make my accuwaether widget gone or make my launcher got that bug
and knox release since s4, should be those samsung phone after s4 ??
they will scan the barcode that you will saw it when remove the battery

yup exactly
but developer got their ways to root it without tripping knox

but I thought once successful root without tripping the knox then can do what you want like flash custom recovery, kernel, etc ...... ???

btw I just notice new twrp recovery is out
