I'm very sad about this Opera's suicide marketing movement of killing "Presto" version to be another Webkit fork.

New Opera versions lost features used by loyal users, like F12 to be able to disable javascript, connectors and site options, F4 to fast access to bookmarks and other functions of left pane, minimized MDI windows (my favorite), the very fast and usefull feature of selecting some URL and open it clicking on gray backgroud area, size of windows in the title and may other usefull features for advanced users and web developers.

I can understand the change to a new render engine, but not to remove all the original and usefull features that make Opera a different and better browser.

Personally I will keep Opera 12.16 as much as I can, but the world is moving. The last Wordpress release make Opera 12.16 unusable to edit new posts, so I'm slowly moving to Firefox, not to the new Opera, because there is no a single advantage to use it.

I'm a Opera user since 1996, I was a pay user, I would be willing to pay up to $50 a year to have back the lost features, but, you prefer to throw all your loyal users in the garbage.

Good luck with your new policy.
