Opera now (half) officially supported for the admin (and Konqueror too)
As I tested Opera 8 yesterday and realized that it works quite well with the latest Opera 8 releases, I invested some time and fixed some remaining CSS problems and all looks good now :) In the same go, I fixed some MS IE issues with the blog editor, so that should look better now, too.
The "half" in the title means, that it will not be thoroughly and always tested by us in the future, so new issues may leak in in the future. And for example the cropping feature of the image editor doesn't work either and we don't have any plans to fix that :) And dbforms2 has some issues as well. But that's the same with Safari and currently IE. We'll fix it for IE, but Safari (and maybe opera) is still lacking some XPath features, AFAIK, so that won't happen soon.
Update: Konqueror 3.4 also works ;)
