It would be nice to see a lot more intergration with the excellent google, in IE I use the google toolbar - some of the features from that (one-click search for web/directory/usenet/etc direct from the toolbar), plus you could have some others (such as one-click translation, just load
http://translate.google.com/translate_c?hl=en&u=<current page url here>) and so on.
Thanks
Tom
