It's been a while since I started working on Ubiquity for Opera. It's my limited, but for me totally awesome, port of Mozilla's Ubiquity project, originally only for Firefox, to the Opera browser.
I had several people ask me through my blog or email to write a version for Google Chrome. And, by popular demand, here it is! To my surprise, it took much less than I had originally thought. I had a few small problems though, from the event handlers, different from Opera UserJS model, to style attributes for dynamically created elements, and other minor things as well.
It's still lacking Ajax/xmlHttpRequest support, but that shouldn't be a huge problem.
I uploaded it to userscripts.org too. You can see it here: http://userscripts.org/scripts/show/85550.
The code, as usual, is up on Github
If you try it, I would be interested to know what you think. Have fun!
