What is unintuitive? Enter to enqueue music, Space for pause, Left and Right arrow to change the track. Backspace to clear the list. Escape or q to quit.
The thing that might throw you off might be alt+enter for enqueue + immediate play, which doesn't happen with enter if something is already playing. It's pretty easy to get used to though.
I'm not the developer of Chroma, you'd have to ask them. I think it looks cool though. You don't need it to run kew.
The explanation that was given to me: "the flake references this repo as a source. You don't need to manually bump versions - when users run nix flake update, they pull the latest commit automatically. So it's mostly self-maintaining since it tracks the repo directly."
It's hard to compare. I really like Winamp and it is one of the players that I respect. kew differs in that it has a library explorer, more importance given to the album cover and a bigger spectrum visualizer. We are still working on visualizations though and were supposed to have cool visualizations this version, but hopefully the next will have them.
Nice!
