This issue is being tracked already:
Issue 1041 – Optionally show elapsed time on the transfer queue list and keep it displayed after transfer finishes

that feature would be very nice

Tks

Thanks for your suggestion.
We will see, if more people ask for this.

Yes

Do you mean a time, when did the transfer task complete?

I think thats a good ideia to have a new columm to show the timestamp for the time of the transference of the file(s)
