Actually it depends wether you have an active or a normal nugget. Normal
nuggets are only rendered if the page that uses them is rendered. So the
usual navigation links show up on pages that are rerendered because of new
entries that apply to them. If you want to change all pages in your system,
just rerender the weblog entries, for example.

Active nuggets are different: the rendered code in the page itself just
calls a JavaScript entry. The nugget is written as JavaScript code and
integrated in the browser. That way you can have parts of your page change
without the  need of a full rerender of your system. Active nuggets are
rendered when they themselves change.

You can trigger both full tool rendering or active nugget rendering with
timers, if you want to happen in every night for example (that's what I
usually do - just set up timers that rerender several tool content pages
each night).

You need to keep in mind that PyDS+PyCS is static HTML + some infrastructure
in the end. So to change stuff, you have to regenerate the HTML and upstream
that. Page contents doesn't change just because of data changes, except when
the code triggers a rerendering. Adding navigation links doesn't trigger a
rerendering, as it would have to rerender the full site - navigation is on
all pages.
