How to use:
After obtaining the size controller, simply right click it to open its GUI. From here you can either type in your preferred size in the text box or use one of the quick access buttons to quickly change sizes. The button with the letter P lets you change whether or not your scale resets after you die.
Pressing the swap button (button next to 'set size') will take you the the other mode.
In this mode, you will be able to change the scale of entities. To do this, open the GUI by right clicking and set a number. After doing so, sneak + right click on an entity to change its scale.
