Some Questions:

[Anonymous]

1) How would I know if someone pressed either Ok, or Apply in the Preferences screen so I can save data?
2) How would I put the user in globally away state?

Thanks,
David

you get a callback into plugin_main and sent an event

if (!_stricmp(event, "prefsAction"))
{
struct plugin_prefs_action_t    *ppa = (struct plugin_prefs_action_t *)data;

        /* Take action:
         *
         * 0 - Cancel
         * 1 - Apply
         * 2 - OK
         */

Should have had that a bit clearer.  You need to check the action type e.g.

if (1 == ppa->type)
{
    writeConfig();
}
