FTP client with one button/shortcut, nag screen free syncing??

Can you guys tell me which FTP clients allow for the simplest, most streamlined upload capabilities. I want to press a single button (or shortcut) and have all the files in the local directory sync'd to the remote directory. I don't want to be bothered by any confirmations.

I'm currently using forklift and the confirmation dialog is really irritating me. When I'm making multiple, small color tweaks in Photoshop >saving them out as jpegs> then uploading with an ftp client every second added to the loop greatly increases the time it takes me to complete my work. I want to just switch to the ftp client, press a single button, then move on to the next app in my workflow.

 

I'll give it a shot.
