Just as you've added WhatsApp and other medias to the sidebar, adding an Email inbox to the sidebar could be really helpful, instead of opening a new tab and loading the inbox, a simple click of a button on the sidebar will open the inbox in a pop-up window. Considering that most of the Email usage today is activating accounts, the pop-up may just give the 3 most recent mails with an option to expand the list to the full inbox.

RE: How to remove the Warning message in Dev Console?Opera for Windows
To sum it up for the confused, developers are frustrated with this change because it blocks valuable real estate in the DevTools console.
While the general concept of warning regular users that they could be a victim of a scam is a great idea, developers should have an option to turn it off, be it in the DevTools settings or Opera settings.
The solution provided in the Stack Overflow link worked like a charm for me, but it is still frustrating that the PMs at Opera didn't think this through.
Hopefully, the Opera team can swiftly release an option to disable this warning.
