Hello, I am an Opera GX user and I really love the browser. Here are some features that would drastically improve the browser and put it above the rest:

• Built-in translator.
• A little more customization in terms of the interface.
• The ability to create browser themes and share them with the community.
• An option that deletes All Data like the browsing history when you close the browser.
• The ability to change the cover by uploading images on speed-dial sites.
• The ability to hide the bookmarks bar, except in speed dial.
• The chance to earn GX cryptocurrency while browsing.
• Improve data synchronization with opera account to save bookmarks and speed-dial.
• Built-in password manager service encrypted with zero-knowledge security model (like "LastPass").

I am aware of the difficulty of implementing all these features, but I believe that this is possible in the future, and that will make your browser stand out from the competition.

Thanks to the Opera GX team for considering my recommendations.
