Rated 5 out of 5 stars

An excellent plugin - *thumbs up*. It's a little bit slow to load Wolfram Alpha results but whatever I'm sure it will be optimalized in future...

This review is for a previous version of the add-on (0.5). 

Wolfram Alpha load speed

Hi Honza. Thanks for the comment. The add-on starts loading the Wolfram Alpha results only when Google has finished loading so that can cause some delay. But I think the main problem at the moment is the heavy load on the Wolfram Alpha servers. I'm sure that will be improved over time.
