I doubt that will happen because as far as I know it's licence does not allow it to without permission from the author.Unlikely since the developer hasn't made an update in close to two years. The minecraft forum has said that the dev has gone entirely from the web. Unless someone else picks it up and ports it... there won't be a 1.10.2 version of witchery
Um you have to enable cheats to spawn items in. Also you have to click the wrench icon and turn on cheat mode in JEI. I have never had a problem with JEI over NEI the main problem I see people have is they are used to the way NEI works and they assume JEI works the same way to do the same thing.Why does this have JEI not NEI? I was delighted that my favorite modpack got a new version only to find within 5 mins of loading it that with the current inventory mod it is unplayable for me. JEI won't even let me hack in Items because for some reason I am not a Server Admin on a Single Player Server (What was the even the point of making single player require servers?). This would not be a Problem if not for the fact the new lanucher does not seem let me disable Mods so I can't even install NEI because it would conflict.
Edit: Found how to change what mod are installed
