I like where this is going makes it easy for the user to setup a server, I also code plugins for fun. Only thing I can think of is for the stack controller page have it load the default items value by looping through the bundles/items and get those values to start with. On the category add a left/right button which will multiply the actual change of the default stack size for the items when the user changes the value so like ammo for pistol is like 64 have the control multiply by the int 1,2,3 and show the new stack size. May be a bit of work but would make it 25 stars!! lol anyway great work on this plugin and thank you.
