Doing this would involve storing the user preferences (i.e. all the cgi
arguments associated with a user) on the server. If you have a close look at
collectoraction.cpp you'll notice that the collector does exactly that. It
does it for a different reason (because all the collector arguments become
too long to be passed around in the URL) but the concept is the same.

So, it probably wouldn't be difficult to extend this to work for the entire
system - would take a bit of C++ hacking however. There'd also be a few
complications like the fact that some arguments are collection-specific and
so shouldn't be stored with a users profile (to do this properly you should
extend the cgiarginfo class so that arguments can be specified as being
"storable").
