  • They should add a calculator to opera, looking for the windows or google calculator is a bummer, the opera sidebar is perfect to have an elegant and easy-to-use calculator

  • One workaround is to try this sidebar calculator extension

    Another workaround is to add any page you want that has a calculator to the sidebar. Goto the URL opera://flags/#sidebar-site-panel, enable the flag, restart Opera, click the 3 horizontal dots at the bottom of the sidebar, scroll down to "Custom site panels" and add the URL to the page. You could add https://www.google.com/search?q=calculator to the sidebar for example to always get the Google calculator.
