Second build for Opera 28 developer has been released for Windows, Mac and Linux, and is available to download. This build has added a trash folder for the bookmarks. When you delete a bookmark, you can find it in the Trash folder. Bookmarks (heart) menu has got an improvement, it now lists top seven most recently used folders even if they’re deeply nested, previously it has only displayed the top level folders.
Opera 28 developer
Mac version got two improvements: "In full screen mode on Mac, the menu bar will no longer slide down on top of your tab bar".
Opera on Mac now uses a different compression format which decreases the file size of autoupdates and network installations by one-fourth." If you use the latest network installer you will benefit right away. Those using autoupdate should get the benefits from the next build onwards."
