I found Steps - http://jondavidjohn.com/blog/2013/06/capistrano-output-cleanup-with-steps - that makes the cap deploy process look quite beautiful. Checking it’s source it seems that v3 and it don’t (yet) play nice together - https://github.com/crowdfavorite/gem-steps/issues/9
Wondering if anyone else has samples or links to share that turn the deploy process logs into slightly more human valuable information?
Well Capistrano’s default log format is pretty but I guess that’s subjective 
I haven’t come across any nice formatters for v3 yet. Here’s the actual pretty formatter class: https://github.com/capistrano/sshkit/blob/master/lib/sshkit/formatters/pretty.rb
It would be pretty simple to do minor changes (if you know Ruby) but a little more complicated to do nicer things like Steps did.
One simple thing you can try is reducing the log level from info to warn or error. That won’t make the output nicer, just less verbose unless something goes wrong.
