I am looking for a download manager that has the following features:
- Open source because I want to contribute, so I am looking for a download manger which is open source.
- Compatible with Windows. It would be nice if it is multi-platform.
- Like Internet Download Manager (IDM); it can download from YouTube, Vimeo, etc. websites (very very important to me). With IDM running, if a user opens YouTube or Vimeo and plays a video it pops up a "Download" window (small window at the corner of the video). Clicking on that window then starts the download. It even asks you what kind of video quality you prefer. I haven't found a open source download manager that can do this.
