Currently the UI Enhancer is saving a cookie with a name and value and leaving the other cookie fields as default. We may wish to provide the ability to save the cookie with non-default options.

Some useful references for cookies in javascript:

The following is a typical cookie string assigned to document.cookie:
document.cookie = 'ppkcookie1=testcookie; expires=Thu, 2 Aug 2001 20:47:11 UTC; path=/'

The format is generally:
1. First the name-value pair ('ppkcookie1=testcookie')
2. then a semicolon and a space
3. then the expiry date in the correct format ('expires=Thu, 2 Aug 2001 20:47:11 UTC') - if this is omitted then the cookie expires at session end (closing the browser)
4. again a semicolon and a space
5. then the path (path=/) - if path is omitted, the path is the current web path (possibly a single page)

JQuery has a cookie plugin http://plugins.jquery.com/project/Cookie - I'm not sure if this is the way to go
