A team I worked on years ago had a build system with an insane number of options. Someone made a GUI that looked vaguely like this OpenSSL GUI does, only it didn't have a "Build" button, but a textbox that showed you the command line options you had picked (I think it could automatically save to a script as well).
It was such a useful tool. I've endeavored to recreate that a few times in other teams when I encounter a tool with a --help that's more than a page long. Really helps new people figure things out.
I was just wondering if this existed yesterday. LetsEncrypt is out there for real certs. I need a site cert for local development. Why can't I type my hostname and mash one button?
No, I had the same thought. Moreover, a GUI/TUI would actually allow implementing some further usability improvements. And there could be a “save as script” option.
