More RT 4 (or can it be done in RT 3.6.3?)

I would like for my users to be able to chose settings like how often
pages refresh or whether a reply or comment is the default on an
individual basis.

I like my RT page to update every 5 minutes but several of my
developers would prefer to have that happen only when they hit the
refresh button, for example).
