Please add these two features Rated 3 out of 5 stars

This is a great addon with great potential. I have withheld 2 stars for 2 features that will make it more usable:

1) A button to toggle the toolbar
2) Ability to add more search engines, either manually, or from the firefox search bar

This review is for a previous version of the add-on (2.3.1-signed).
