When you search for a file, it is so easy to double click on a search result and add it too you transfer list....

OK, so now I have 200 or so files added to the transfer list and many of them have the status "Searching, busy 0, buffer 0", which I assume means that there are not peer or ultraleaves currently on-line that have my file. No problem. Its just that some of these files stay that way for a very long time, or maybe even forever.

I assume that Xolox is using up processor time and bandwidth looking for these files, and its conceivable that it could keep looking for these files forever. Perhaps you could add a feature to keep track of when the file request was made. You could make this another sort field and even add an option to automatically remove files from the search list that are older than a certain date.

This is a good idea, could even be based on not searching for a file after so many attempts.

I'd cancel 90% of those requests and begin starting over, and yes those are just likely wasting traffic and resources now.
