Inventory Tweaks Addon for MCPE

You’ll basically be able to have full access to the creative inventory while in survival mode and vice versa. As much as it’s useful for single player use, there’s no denying that it can also be used for malicious intent. But don’t worry, further down on this page you will find information how to protect your server against possible misuse.

The first thing you’ll need to do (assuming you are using a tablet or a smartphone and not a computer) is to set the user interface profile in Settings to Classic.
Press the inventory button to open the new inventory menu. Even though it’s not possible to see, I really was in survival mode all the time while testing this addon. But it doesn’t really matter which gamemode you’ve enabled since it works for any of them.You can access the same types of tabs as before but the difference now is that they are explained by text instead of icons. E.g. “Tools”, “Miscellaneous” and so on.
