Losing an Opera browser session can be annoying, especially if, on re-launch, crash, or a sudden OS reboot. Users may have the history in order to find individual tabs that were closed; However, if you were browser the web with multiples tabs, finding the right tab can be quite a challenge. Thus, having a via to restore an entire lost session could come quite handy. Other browser have this feature build-in with the key combination of Ctrl+Shift+T or via the history.

Browse much more privately with Tor (build-in) on Opera Private Mode

Opera could have a "private mode", but this only hides users history from others using the browser. But if Opera could have Tor (build-in) on private mode, this could add another layer of security on the browser.

I love Opera, I think is one of the best web browsers now a day; However, I think it missing some important features.

Now a day any browser such as chrome, brave, Firefox, MS-Edge have the option to reopen all web-tabs that were open at the moment the browser was closed. If you have 5 web-tabs open and by mistake or computer error the browser close you can recover your last web-tabs session by pressing "Ctrl + Alt + T" but not in Opera.

Additionally, MS-Edge adds a feedback button on their web-browser which makes it easier to report any web page error with browser incompatibility or to suggest any new feature to the browser without the need of going to a forum.
