Is it possible to remove these configurable prefixes like @, !, . etc. and add only a search engine letter (shortcut) to switch between search engines ? Would be great If you could search via query "Google shoes" instead of "@Google shoes"This review is for a previous version of the add-on (0.7.8.20110620.1-signed.1-signed).
You can set and use search engine keywords without the operator. HTH.
