drop item and bank limit script

can anyone make me a drop item script and a bank item limit script ?
I am using the item limit and the item storage scripts of game_guy.
It should be nice if someone can make a drop item script : a edit in the menu so you can use or drop an item or something.
and if someone can edit this script from geme_guy so you can set item limits for the bank accounts.

 Item Storage Script
 Author: game_guy
 Date: May 1st, 2009
 
Introduction:
If you've ever played any of the Elder Scrolls series or Fallout series than of
course then you would have noticed the awesome item storage. This script does that

Features:

• Store Items in Chests, Closets, etc.
• Have seperate closets and chests
• Easy to use

Instructions:
Use a simple script call to open the chest.
$scene = Scene_Chest.new(x)
x = the variable id that you want the chest or closet to store items and stuff in

thats all give proper credit.
