yeah another +1 here.
i'd still like to use google but google.co.uk not .com so that i get the option to filter the results down to just pages from the uk. this is an option i use daily.
i've saved a google.co.uk tab which works provding i don't already have a google.com window open. if i do have a google.com window open, the google.co.uk tab just opens that window which doesn't have the option to filter the results.
