Request make --progress-only human readable
I often use --progress-only to check how long a specific attack would probably run, but i allways have to convert the given runtime manually to a more human readable format (days, hours etc.)

is it possible (yeah of course ^^) but could there be in a future release a 

--progress-only-human option?
Seems reasonable, or at least to find some way to address the issue. I'd open a GitHub issue and request it.
