It's really cool that Gephi Lite allows one to write their own custom filter, I was having a headache trying to compose a complex one with Gephi's Reverse Polish Notation system and felt like gephi lite was gonna save me with this feature.
Although, I was a bit disappointed when I opened the code editor interface because the template given provides the form of the function and documentation of the parameters, but there are no example anywhere, neither on the non-custom filters (being able to read the corresponding code would be great), nor within for instance a commented example within the template.
