RAdmin 3.5 File Transfer is VERY basic, needs more usability features like a file transfer monitor on the Server side. Would be helpful to actually know who, where from, and what file is being transfered. Just having an active connection that states file transfer isn't very useful.
Would like to see more admin features like being able to probe who's downloading what file in real time, and in logs. Kinda like the "Spy User" feature in the old FTP program Bulletproof FTP.
