The icon idea is cool. I do something similar but optimized for searching rather than identifying. I put a "tag" in front of my commands. Then I can type the command and press up. For example mc= sexec nix-shell -p jdk17 prismlauncher --run 'exec prismlauncher -l 1.19.4 -s mc.example' Will start the right version of Minecraft with the right version of Java. I just type mc<Up> to find it. I use this for commands that I know I will want to reuse, but not frequent enough to always be near the top of my history. In this case I could probably search for "prism" and it would be good enough but for things like specific ffmpeg incantations it is hard to remember a unique part, so the tagging lets me give my own name to the command.
