 ## Issues and PRs
 
 You are welcome to open issues, but please be aware that this is a hobby project written to help me learn Rust, and as such have no ambitions to a) implement features I don't want (though you are free to open a PR and I'll have a look at it), and b) fix issues that don't plague me personally (unless I feel it is large enough to warrant a fix).
