This mod for Pocket Edition was developed by HellPie along with the help of MCMrARM. What it provides is something small – but it is extremely helpful and useful. It of course forces more slots on the hotbar in-game, nine to be exact!
In order to install this mod, you must be using BlockLauncher beta for 0.11.0, which you can download here. If you would like to read, clone, or compile the code used with this mod, you may find it here.

All in all, this mod is great! The amount of hotbar slots Minecraft Pocket Edition provides by default is not enough, and everyone knows that! So why not give this a shot?
