None of them do what I want. And I'm not the only one.

The new way is easier to use because the same thing always happen when you download a file. But some control of individual >files is taken away to achieve this.
It is a simplification of a regular task that did not need to be as complicated as it was.
Click on a file download link, let it download, and then double-click on it. Having an Open dialog would require us to have >a Save dialog too. This is not likely to change.
And some more comments about this approach and that makes life easier for users with no experience!
It makes no sense! At least, make "open" an option! Or an extension / power user...
I want to open a Zip file, extract the content and Opera automatically delete the temporary file after closing! Same to flash updates, small programs, etc.
I don't want to download, open and then navigate to folder and delete the file!
Opera is dumbing down and limiting user choices...
