Tabbener is a free Chrome add-on developed by denizaydemir. Designed specifically for MacOS, this handy tool enhances tab management in the Chrome browser.

With Tabbener installed, users can open a new tab next to their current tab by simply pressing Cmd + Y. This feature eliminates the need to manually navigate to the new tab button or use the right-click menu. However, it's important to note that this shortcut conflicts with the default "Show Full History" function in Chrome. Users will need to go to the Keyboard settings and create a new shortcut for "Show Full History" in order to use Cmd + Y for opening tabs.

It's worth mentioning that Tabbener is unable to open tabs from Chrome's system tabs, such as those starting with chrome://... or about:blank. Aside from this limitation, Tabbener provides a convenient way to open new tabs in Chrome, improving browsing efficiency for MacOS users.
