It would be handy to have a little button below the current Assistant query slider within threads that transports the user to the bottom of the page and thereby to the query entry box. This would be particularly handy for lengthy threads with plenty of content to scroll through.
What I am essentially asking for is a visual expression of the command+arrow down shortcut that currently exists on macOS. It would probably be a darker shade of the existing arrow down button, or have something else to differentiate it.
