Try the Tidy Bookmarks extension for Opera. In addition to the personal toolbar at the top of your browser, you get a more traditional view of your bookmarks with a vertical display if you click on the icon (with a star) that is placed on the top right of your browser.
On more support for Chrome, I just discovered you have an Opera Extension that lets you use Chrome extensions. It's called "Download Chrome Extension." It lets you use extensions in the Chrome store. After I installed that extension in Opera, I downloaded the Chrome extension, "Share Link Via Email," which was exactly what I was looking for. I can now, right click on a link, get a context menu, and send the link to a friend or associate via the mail program of my choice. I tested it. It works.
So all of the Chrome store extensions seem to be available. This is, I think, very useful!!!
