GUI Disposition

If you want to change the position of the item there is something called "GUI Disposition" that you can change for every GUI inside the plugin.

Let's look at an example and try to understand it.

- "---------"
- "-c-btmls-"
- "---------"

The - are the empty items, c is the Cancel item, b is the Biome item item, m is the Money wage item, l is the lose inventory item and s is the Send item. Here is how it looks ingame.
