when you want to copy an item for a addon script just do [addongen a gump will come up -check all the boxes to be sure you get all the items
you will see 2 buttons to gen and to gen and test-I like the Test & gen as it allows you to place the item-this way you will see if all of it was captured.
Also once you have the script- this will be found in The Box folder- when you open the servuo folder you will find it there. This is auto created with the addon generator script- so all scripts you will find in there, then move to your custom folder
