About CNewItemManager
Give custom item library plugin
I used this plugin to manage all my homemade items.
It doesn't make the item work at all. It just avoids repeating code in different plugin. I used it more like a library.
The default configuration is the one I was using for my server. My objects may be useful for you. If you want to use only the steam id. Some of them are on my workshop
