Need some improve on InvX_1.8 system

I found InvX_1.8 system a great inventory system.but i still need some change,because i am a layman ,i need some help
change:
1.when an item is equiped,make it disapper in the main inventory,i mean the item can be seen by pressing the "check Equipment" button
2.when an item is unequiped,and drag to the "Cancel" button,make it appear in the main inventory again ,if the main inventory is full ,please show error "The inventory is full",and do noting
3.Disable the auto equip function

please help me ,i sent it from China
thank you

You are actually requesting some stuff that is very hard to make, (on top of InvX that is)

#2 doesn't make any sense, if the item is unequiped it would already be in the main inventory.

Sorry to bother you ,but thank you all the same
I find Caster System a great System, and Vexorian a genius
Thank you, I hope I can introduce the Caster System to the Chinese WEer,
