If you try to hook the PickupContainerItem function on your addons and you want to disable the engbags alt+click support for some functions, set these variables to 0, you can disable Alt+Click on trades/mail and auction separatedly.
EngBags_AltClick_Auction = 0;
EngBags_AltClick_Trade = 0;
EngBags_AltClick_Mail = 0;

EngBags add support by default for alt+click trading/auctioning (simple)/mailing (simple & massmail from ct_mailmod), if your addon do it too, disable my functions with this to avoid conflicts. (I can't make an if for every mod that do that ~.~)

EngBags is the combination of EngBank and EngInventory. Many of the functions are now shared between the two bag mods.

Command line configuration:
