About this Add-on
Just do a search on Google and the Wolfram Alpha result for that search will appear on the right side.
Take a look at the screenshots and you'll understand how it works.
As the Google sidebar takes up a lot of room I changed the behavior of the add-on so that it replaces all the Google content.
This also means that Wolfram Alpha results do not automatically appear. You always have to click to see them but they get loaded in the background so it is fast.
Thanks to everyone for supporting this Add-on!
