Add toggle button in chevron drop down to prioritize recently overflowed
editors In the workbench, the chevron drop down shows all editors, including those that cannot fit in the main editor area. By default, these editors are ordered using a comparator, which makes it harder to quickly navigate to editors that recently moved into the chevron due to overflow. This change introduces a toggle button near the filter text in the chevron drop down that allows users to switch the order to a new one. This new view displays the editors that most recently moved into the chevron drop down at the top. Activating the toggle displays these recently overflowed editors first, providing quick access, while clicking it again restores the normal display order. This feature improves visibility when there are so many editors that are open in the workbench window and editors overflow into the chevron at the same time.
