Client: Show Connection # in Log

[blujay]

While downloading several thousand small (few KB)
files, I turned on 4 simultaneous connections to speed
it up. When downloading such small files, the speed is
held back by waiting for the server to start sending
each file, so by running many at once, the overall
transfer speed stays more constant.

I had to pause the download, so I unpressed the Process
Queue toolbar button. Then when I resumed it, I got
some failed transfers. Files were created with the
right names, but with 0 bytes, and they were removed
from the queue. As a result, I'm going to have to
start the transfer all over again to be sure I get all
of the files. :/

I was going to report a bug, but there is a problem:
With multiple connections, you can't tell which
commands and responses are on which connection, so you
can't figure out which transfers failed! I have
included an example at the bottom.

As you can see, it's impossible to tell which commands
and responses are for which connections, so you can't
tell which ones are failing and which are succeeding.
A simple change to something like:

[1] Command:
[1] Response:
[2] Command:
[4] Response:
[2] Response:
[4] Command:
[3] Response:

Would show which commands and responses are for which
connections. They could also be color-coded. Also,
you could use a drop-down box to choose which
connections' logs you wanted to see in the log pane.

If this is implemented, maybe we can track down this
bug that caused the zero-byte files.

Thanks.
