Download Queue is a download manager. It supports multiple connections; the HTTP, HTTPS and FTP protocols; and full resume and authentication support. Downloads can be controlled manually or scheduled to run, and optionally stop, automatically at a chosen time every day or just once at a particular time and date.
It's also easy to manage your downloads which can be searched, sorted and filtered using various criteria. And then once you've downloaded a file it can be opened with a double-click or moved anywhere just by dragging and dropping onto a folder in the Finder, all from the Download Queue window.
Optional Safari and Firefox extensions can be installed, providing seamless integration with your browser.
Applescript is also supported: you can add/remove and control downloads from your scripts.
