I really like this, I think I'd find it useful fairly often and I like the idea of just making something that I use irregularly but not that rarely a bit better.

But then I found it's in C#. And apparently the CLI app isn't even published any more (apparently nobody wanted it? Surprises me but ok). Anyway, I don't think I want this enough to install .NET to get it, so that's that. But I'd have liked a version in Go or Rust or whatever.
