Allow multiple Stat Boost's
For example: Attack +3, Defense +1.
Allow Custom Stats on Item's
For example the player creates a custom stat called "mana" you would be able to Stat Boost that stat on the Item.
Allow Random Stat's and Random Stat Value on Item
The Player would set what Stats would be able to randomly be chosen on the Item and the range of the Stat. for example you set Speed 1 - 3, Attack 5 - 10, Max HP 10 - 20. 2 of the Stat's would randomly be chosen on the Item with a random Stat value each time you acquire that Item. For example you acquire a Sword and its Stats are: Speed +2. Max HP: 12.
Add on Item Pickup Script
This could be useful for many different things. Maybe you want the Item to automatically equip itself when you pick it up or you want a sound to play when picking up the item. ect.
Add option to display Item's Object Model instead of Item's Image when the Item is dropped on a Tile
Add option when looking at Item on ground to show Item's Tooltip
Add ability to split item stack by Shift + Click on item
Add option to display Item's Stat's in Item Description (You can do this already but if random Stat's were implemented you wouldn't be able to dynamically change it)
