This will make it possible to store the compiled Dashy in a read-only directory, and give the config from outside of it. For example, this is needed to package Dashy for Nix normally.
Describe the solution you'd like
Ability to specify another directory for configs and their backups e.g. with an argument. To get something like node server -c /etc/dashy.
Priority

Is this something you would be keen to implement
