I am a long time Opera user and fan and I decided to bite the bullet and install and test the "new" Chromium based version (V25 and Dev. V26).
It's great to see the progress that is being made with the new engine but I'm sorely missing some of the features that are in V12.
Opera V25 imported my V12 bookmarks, great, but they are in a special section called Imported bookmarks that I don't seem to be able to move back into the main bookmark hierarchy.
I know you guys are very busy, but I hope the integration of a more complete bookmark management system similar to the capabilities of the V12 browser is reasonably high up on your to-do list.
Keep up the good work. I really want Opera to be my main browser
Update: OK, I found a way to move the old bookmarks into the main hierarchy.
They just added bookmarks back into the fold a short while ago. Its still very much a work in progress. Advances have been fairly swift though.
