UGet is a lightweight, easy to use download manager that has many useful features such as multiple simultaneous downloads and resume support for large files.
UGet is available in the repositories and is a download manager with many useful options. It can, for example, pause a large download and resume it successfully (if the server supports resuming). It is also possible to queue and classify downloads and allow it to monitor the clipboard for potential downloads. Bandwidth can be controlled per download or on a global scale and, if necessary, you can specify a proxy to use. When flashgot is installed in firefox, uGet can be chosen as the default download manager for that browser.
