I feel like the bottom bar during tab overviews should be customisable. In my case, I would like the Done button to be replaceable by the menu bar button (circle with three horizontal dots), so that I can adjust Orion settings without going on an individual open page.

While the Done button itself mirrors Safari's functionality, my personal preference is to click the tab I want to visit rather than click a button that defaults to the last tab I visited — although, as others' preferences will differ, this should be customisable.
