Google Chrome recently added a tab search button to the title bar. When it was first enabled, it was possible to disable by going to chrome://flags and finding Enable Tab Search and changing it to Disabled.
A quick search of google will find multiple examples of how to disable it. Unfortunately in more recent versions of the browser, it no longer seems to be an available flag to disable.
I realized that my big issue with the drop down menu is it’s location, which Google has located on the left near the minimize button. Google has chosen to not have the traditional windows system menu on the left side of the title bar. The left side would be an ideal location for the tab management button.
