Feature Request: Allow new mirror for partly downloaded file

Hi,
Steadyflow is great! Thank you.

I miss a feature from when I used wget to download my files via the terminal. Sometimes while downloading from sites like Megaupload, my connection goes down and I end up with a partly downloaded file. Instead of starting anew again, however, I just go back to the Megaupload link, wait for the timeout to finish and get a new link(mirror) to the same file. I feed this link to "wget -c" which simply checks if the target filename is present in the PWD and continues downloading instead of overwriting it or starting from anew. Note that this is not the traditional "Pause/Continue" in other download managers but rather a check to see if the link refers to the same file that is partly downloaded.

In Steadyflow, if another target filename is found to be same then the option is either to overwrite it or cancel it...is there any chance to allow it to continue the download using the new mirror?

Of Course this is a pretty narrow use case but I have benefited from it many many times...its a pity that other big GUI download managers don't have this feature, also many people don't seem to know about this neat feature in wget...

Thanks!
