Yeh I think the answer to all these questions is: find the module you want to change, then read how to change it.

Litestep works by loading modules to perform tasks or create objects, then you have to tell litestep (in .rc files) the details of these tasks and objects.

Each module will come with documentation be it great or not so great.

In your theme's directory there will be a "theme.rc" this is the mother .rc file which will (in most cases) contain lots of *NetLoadModule lines followed by the names of all the modules being loaded.

All of those modules are potential culprets (sp?) in your quest to change feature "x".

Good luck :)
