Rated 5 out of 5 stars

Its awesome, this makes total sense. No one will replace Google for Wolfram, but with this add-on, you can get the best of two worlds.
Thank you.

Just a small note: on the Arabic Google. like google.ae the results are already on the right. so the Wolfram pushes them down.

This review is for a previous version of the add-on (0.4). 

Arabic Google

Hi Medopal. I'm glad you find it useful. I just checked out the Arabic page. It shouldn't be too difficult to fix that one so please check back next week for a new version. It will be the same for all the rtl languages so a good one to fix. While add-ons are "experimental" they won't update automatically so please check back here until the add-on goes "public".
UPDATE: Right-to-left language support has been added in Version 0.6. Wolfram Alpha (and the buttons) will appear on the left on rtl pages.
