So far, I have not installed any of the add-on toolbars. I seem to have 'almost' all the functions they offer in stand-alone programs...searching, spell-check, access to GoogleEarth...etc. I suppose Google bar will be ok, but I hear it is kinda hard to uninstall if you don't like it.

(I do have a source for special pre-configured Proxomitron filter setups..I'll post the info soon...)
