"The suggestion to use SYMBALOO does not solve the issue. Symbaloo is a third-party site that is not part of Opera. There are many bookmark-managers/speed-dial type sites on the Internet. Using those is okay, if that is what you want. But suggesting that as a solution to this problem is like saying: If your car is broken...don't take it to the mechanic, buy a different car. It's an option, but not a solution to the problem."
Ah, the insistence of Opera users on speed dial being integrated into Opera browser. Many browsers use extensions to achieve speed dial functionality so I didn't realise that this may be unacceptable for Opera. Is it because Opera was the first to introduce this feature?
Maybe it's time to move on and stop waiting for the glorious past to come back, this thread has been here for a year without anything happening. Do you really believe that devs are gonna solve this issue quickly if they read posts like "I like Opera and will wait patiently for this feature"?
But you know what, you're right that using Symbaloo is not an option in Opera, but for me it is because it doesn't open as quickly as the integrated Opera speed dial does rather than the fact that it is a third party website. As I've recently discovered it is not the Symbaloo's fault, but it is because Opera is too slow to open it. Maxthon for instance opens up Symbaloo much faster and apart from that it offers an installation of fully customizable speed dial extension, which has nothing to do with Symbaloo. I know, that probably wouldn't be an option for Opera users, would it? 
Sorry for the rant.
