This is not something I’d ask of developers, but I like having a GUI for initially learning all the options and flags. It’s nice having a visual of which parameters are allowed together, where order matters, which ones accept arguments, etc. This is partly how I learned Ffmpeg back when I was still using Windows.

Once I’ve got a high level understanding, then I’m headed for the terminal.

Realistically I have a text editor putting a script or complex command together with the man page open on another screen. Not as friendly but generally works.

I don’t see TUIs a lot. Usually they are very linear. Would be interesting to see one with more of a 2D array of options.
