Kudos to them. Opera gave up on this dream being unable to accommodate all the nuances of web standards and accounting for out of conformance behaviours that many websites rely on the daily.
I reckon this browser will need to be at least on par with reasonably recent version of Firefox to see significant adoption.
I do too. What a joke the browser became after moving to Chromium... I remember it didn't even have bookmarks in the first version.
On the flip side I kind of understand the decision to pull the plug - if you've looked at Browser.js and think that potentially any site might need a fix to work properly...
