Menu Info
When you open the GUI by typing /morestuff a 9x6 inventory will open up, you have 8 options to select.
Weapons
The first one is a Diamond Sword named 'Weapons', upon clicking this you wil get another inventory 9x6 open with 3 selections, Regular Weapons, Ranged Weapons and Magic Weapons, by clicking one of these you get a inventory full of what you clicked.
Accessories
The second one is a Diamond named 'Accessories', when you click this you will get a 9x6 inventory full of items players can use to either defend themselves, jump high, or even just some fun stuff.
Armor
The third one is a Iron Chest plate named 'Armor', when you click this you will get a 9x6 inventory. This menu contains 6 sets of armor so far, each with their own abilities apart from fur armor.
Tools
The one is a Iron Pickaxe named 'Tools', when you click this you will get a 9x6 inventory. You get 6 items in this menu each with some really cool and helpful effects.
Mobs
The one is a Plain Monster Egg named 'Mobs', when you click this you will get a 9x6 inventory. 3 mobs are within this menu, all hostile at the moment but i will be adding some passive mobs later on, you can find Demons & Demon Kings in a soon to come 'Demonic Castle' generation, same with the goblins but in a 'Goblin Dungeon' generation.
Spells
One of my favourites this one is a Plain Enchanted Book named 'Spells', when you click this you will get a 9x6 inventory. You will see 5 spells, each with their own very cool abilities and very helpful, but a little over powered in some points. You can remove mobs instantly, or even throw them 10 blocks high.
Miscellaneous
This one is a Slime Ball named 'Misc', when you click this you will get a 9x6 inventory. You get a bunch of very cool items most a little pointless but a phew quite handy for example, the Bomb Defuser, you can use this to right click on a tnt and it turns back into its block form, to find more information on the Bomb Defuser click on the one above.
Items
This one is a Bone named 'Items', when you click this you will get a 9x6 inventory. Proberly the most use menu of the plugin, this adds some really cool items, it adds 5 new throwable tnts, some really cool projectiles, and some really awesome stuff
