Spark client & File Transfer Resume

I know that Spark is not a FTP client, but is there the ability to suspend/resume file transfers with the capability of allowing users to resume interrupted transfers; pause and resume a file transfer as needed? I ask because I have remote users who send each other rather large files via spark (instead of clogging up the email system with huge files), and they note that sometimes it will drop the connection, and I’ve had it drop on me at 145 MB of 150 MB as well (not over local lan, but via broadband to remote users).



Would this fall under more of a bug report or feature request, if so where would be the better place to submit this?
