[Desktop Entry]
Version=1.0
Name=Opera
GenericName=Web browser
Comment=Fast and secure web browser
TryExec=opera
Exec=opera %U
Terminal=false
Icon=opera
Type=Application
Categories=Network;WebBrowser;
MimeType=text/html;text/xml;application/xhtml_xml;x-scheme-handler/http;x-scheme-handler/https;x-scheme-handler/ftp;application/x-opera-download;
Actions=new-window;new-private-window;
[Desktop Action new-window]
Name=New Window
Exec=opera --new-window
TargetEnvironment=Unity
[Desktop Action new-private-window]

Exec=opera --private
TargetEnvironment=Unity
And save it as opera.desktop under ~/.local/share/applications/ .
