I'm a die hard vimmer and have never heard of Ranger. I'm looking forward to using it more. I asked a couple of my online Linuxey buddies and they used it years ago when they had less substantial machines. I still love the command line stuff even with my best machines. Everything is super quick in the terminal. 
Thanks for the mention and your great shows. 
I need to explore jq for sure. I work with a database that saves a couple columns in JSON. It would be nice to query the exports in a more friendly way.
