At my home setup transmission is running on a (semi-) headless mac mini, which I administrate useing a macbook pro. Often I'd like to add 5-10 new torrents at once. So far the only alternatives I've found is to drop files in the watch-folder (which requires me to open finder, connect to the mini and finally navigate to the folder), or upload them one by one in the web-interface. It would be much simpler and faster if could just drop the files in my already-open browser window

As both Google Chrome and Firefox 3.6 supports this feature now, there should be quite a large group who would benefit from this feature.

I'd also like to point out that a similar request was made about a year ago:
