How to orphan native LL code?

Hi,can anybody please tell me what I have to do to overwrite native Livelink code. I didn't find anything in the Online help nor on the KC nor in the Builder documentation though this is indeed an faq.In my case I have to extend the Presentation tab of folders. Therefore I have to extend the extendedData field. I understand how to change the Weblingo files to get the expected results and also implemented the functionality by changing the native Webnode OScript (methods WebNode:WebnodeRoot:WebNode:0Setup() and Action-Catalog2()). Works fine on my development system.I understand well that it is not the right way to change native Livelink code and would like to have my own module doing all this. My Questions: What exactly do I have to orphan (the WebNode:WebnodeRoot:WebNode-Object? Only the methods?) and how does overwriting work (automatically, changing the request handler)? The plan is to have an additional Checkbox to specify weather the Description from the info page is shown with each entry in a folder's List or not.ThanksCarsten
