Make a firefox plugin
The plugin could manage the downloads. It could create new uploads. It could do anything that could be done through the browser. Could be done with xml or something else.
MAKE A FIREFOX PLUGIN. DO U KNOW HOW MANY PPL USE IT? CHECK WIKIPEDIA.
After Bitlet 4 Chrome, Bitlet 4 Firefox... why not ?

The Firefox plug-in would also allow you to continue uploading without the window open

Simple, assuming you use a recent version of windows. Make a batch file (.bat), open it in notepad, and paste in this code:
Save it in a permanent spot, then associate .torrent files with it in Windows (use an bat to exe converter if needed) or your web browser. Upon opening, it'll spawn a tab/window that will load the bitlet applet.

What use would that be for that?
