It would be great to be able to see how far along an FTP or SFTP transfer is, via a progress bar or even bytes transfered out of total bytes.

There is Transfer window that shows this.
when file size is known it shows NNN of KKKK, and when it's unknown, it shows NNN.

Maybe I am just missing it, but here is what I have for columns and the content during a transfer:

Task: Copying file (filename.tar.gz)
From: C:\filename.tar.gz
To: [FTP: remote.host.com] /dir/filename.tar.gz
Info: Starting FTP transfer
Status: Transfering...

Then once it is done, it switches the following columns:

Info: Transfer complete, transfered XXX byes (XX B/sec)
Status: Completed.

I couldn't find any options to change any of the display items. I am using Build 4043 from "My Products".

If file is too short or ide took very little time for transferring, you'd not see XXX of YYY is transmitted.

The file is 40 MB and takes about 5-10 minutes to transfer. I am not really concerned about little files since they transfer so quickly, more about the big ones to see how much longer they will take.
