I'd appreciate a 'shuffle' button that just re-mixed-up the letters into a different order. I find this keeps me from obsessing on adjacent letter pairs that my eyes/brain lock onto.
uhhh... that's mostly on your browser. The css is at the top and pretty skimpy. If it really bothers you, find a styler extension that will override the CSS to render it more pleasingly.
>having to eff around with the crap show of Ruby/Python/Node envs and how every person likes to use different tools for setting those up
This was the problem I wanted to solve, and I ended up on nix+direnv (and am considering devenv) because nix, due to the existence of nixos, packages all the tools already! Does Mise support zig? or nim? or crystal? Nix does! And Nix will continue to keep up to date with all the tools, whereas things like asdf and mise - since they're specialized and not the basis of a full distro - are less likely to do so.
