How can I disable very annoying tab preview when using ctrl+tab?

Description: The tab preview feature is highly annoying and made even worse by you devs hiding any way to disable it.

Steps to reproduce: Click ctrl+tab key. I don't want to preview a tab because I can see the name of the tab in the description field anyway.

Expected result: I want a normal tab switcher like in Chrome or Firefox or any other browser. There's a reason tab preview is not enabled by default in browsers - most users don't want them.

OS: Linux Ubuntu 15.10

Version of Opera: Latest version

On the other hand your new VPN feature is great. Thanks for that.

Now - how on Earth can I disable tab preview? I have googled for a long time on several occasions already. Never force users to use particular experimental features, always make them optional but I think in this case most people don't even want tab preview in the first place. It's feature bloat.
