Of course: JS can modify anything on that page.

TT is server side. If you want to manipulate the page without a full 
page reload, you'll have to handle this in the browser, using JS.

LMS uses this all over the place. Eg. the status section top right is 
all dynamically updated.

 From your question I understand you're not familiar with "AJAX" etc.? 
Even less so with the framework we're using, ExtJS?...

It would probably be easiest to look into your existing JS code, the one 
which triggers the pref change. I could probably point you at examples 
of similar code in other places.
