I think I know what you're saying. I had to read it a couple of times and I am guessing.

Are you saying: You would like to be able to stop downloading from a particular host (like when the speed is incredibly slow or gets stuck at 0 kb/s) and try to get it from a new host without killing the download?

I'd like to see that too. Instead of trying to do a new search. Sometimes they don't come up again for a long time. I'd like the ability to stop the download from one user and keep it in my download queue. Sometimes files will start to download without showing up in a result.

Or better yet, if more users would check their upload monitor now and then and kill the 0 kb uploads. Sometimes it can kick back in and start again at a reasonable speed. But if we kill it on our end, we have to search (and find it) again.
