Some initial thoughts: this is similar to jq, which I use almost daily: https://stedolan.github.io/jq/
I hate to be that person that complains about the format of the article, but I get a little confused between the images of the tool in action and the animated images. I found myself re-reading to see if the animated graphs were in some way generated by fx.
Animated gifs just for fun, but yes, maybe they disturbing from artichle.
Thanks for making fx! I use it + fzf for inspecting Mozilla’s CI configuration, I recently made a screecast about this workflow here (disclaimer: I didn’t dig into fx very far, so there are probably a lot of things I said in there that are wrong.. my apologies in advance).
