Sure, I write small python CLI utils that help me solve media organization, media consumption, and sometimes data analysis. I use this every day on Linux and Android but I haven't tested it on other platforms. There are a lot of different subcommands and, although the CLI package will always be opinionated to some extent, there is a lot of niche functionality which might not need to exist. So I'm open to things being refactored or new subcommands being added. [1]
I have a lot of ideas for new ones, for example, I want a CLI that can take an artist name like "Theodor Kittelsen" and fetch highest quality public domain images--but I realize any implementation that does this well will be somewhat fragile so I haven't really attempted that yet. Other ideas that I have are often solved by piping output from one of my existing commands to another or adding some optional args to an existing command.
