That is unlimited items mod where everything you pickup becomes 99+ which is very inconvenient when mining or digging (stacks of cobblestone or dirt fills your inventory). In free crafting mod when you craft something in the crafting table, the items used to make the item multiplies and also items placed in furnaces multiply. So I hope you understand the difference.
Quote from lunearsWhile we work (or procrastinate) on the teleport mod, would you guys want a mod that drops any block you want when you break something?
This mod http://ioscheaters.com/topic/6402-minecraft-pe-095-toomanyitems-mod-best-hack-for-mcpe/?hl=minecraft kind of supersedes the mod you suggested, but a 'Drop Anything You Want' mod would be cool and useful.
