Download Manager Suggestions :
Start with Windows
Start Minimized
Minimize to System Tray
Hide System Tray Icon
Allow RESUMING!!
Allow dragging of files within Download Manager to change the queue order.
Add "Pause This Download" and "Pause All Downloads"
Add a "Download Now" right click command that would override the Maximum number of downloads setting and start downloading that file, regardless of where it is in the queue.
Add toolbar buttons for many of the commands (Cancel Download, Clear, Download Now, etc.)
An automatic FTP search that will search for the file you're downloading on numerous FTP sites and automatically download from the fastest one.
Other things I'd like to see, but really aren't that important :
An indication of how far along each piece of a Fragment Download is. The best implementation of this I've seen is an actual split progress bar, where each split represented a fragment.
Skin support.
That cool new Column Auto-Size technology you guys developed for MJ.
Automatic virus scanning using whatever anti virus software you have installed.
