My tools list 
just got a little shorter, now that
IE7Pro comes with inline search built-in. If that isn't enough, it also comes with its own spell-checker. I discovered this add-on a while ago and it seems to have continually gotten better and better. I'm very happy with it. If you haven't seen it, I'd suggest you definitely check it out. My only complaint is around some of the defaults. For instance, by default, IE7Pro opens a new tab from the address bar and search box. This is a pointless feature, if you ask me because IE7 comes with that built-in -- simply press
Alt+Enter. Opening a new tab from a favorite is just as pointless, seeing as tho there's an arrow that does this exact same thing. I don't mind having these features, if people really see a need for them; just don't make them defaults. Either way, I still enjoy the add-on. Give it a shot, if you're looking for a good add-on. There are plenty of features there, so I'm sure you'll find something you think is interesting.
