Thanks for the kudos! It's absolutely mindboggling how many times I've decided to deviate from one of ls's default settings -- certain that the old way was inferior and outdated, and that the new way will be obvious and immensely popular -- only to find people have no idea why I'm doing things this way! I need the colours to help me scan the output; if I don't see human-readable units, I curse myself for forgetting the flag. But thousands of people don't like this, and it's usually a different set of features with each person, too. I would never have guessed I was so 'out there'!

ls is one of the most entrenched pieces of software there is; this is freeing, in a way, because it provides a stable base for people to rely on, leaving exa free to experiment. Everyone who values stability and simplicity most of all won't be switching from ls any time soon, which means I can push exa more in the direction I want it to go.

(Fun facts: very early releases of exa didn't have a grid mode at all, just the long mode, because that was the only one I used. So there have been some concessions to popularity :)
