As a user switching tabs, highlight the tab that was active before opening the tab list screen, so I can quickly and intuitively get back to my original tab.
Currently the tab list does not highlight any tab (at least in dark mode; see the attached screenshot). Adding a highlight enables users to instantly recognize their last active tab, removing the requirements to remember what the page may have been titled or its URL, and to have to read these items for multiple entries.
Additionally, hitting the backspace key closes the last opened tab (as far as I can tell), rather than returning to the last opened tab, which is confusing and frankly a little frustrating. This would provide a workaround until that is adjusted, if ever.
