1 - Optional. User can show or hide this icon. When the icon is clicked it will show the popup window;
2 - User can decide between "Only remove from the list" or "remove from the list and delete file";
3 - Show file in the folder;
4 - This area will show the most recent downloaded files, so this area could show one, two or more lines;
5 - Size and date of download;

It's just a suggestion that could be implemented, and have a better and different design than the one I showed.
Thanks for taking the time to add the screenshots and details, it always helps visualize it better.
We appreciate your feedback.
