This does not demonstrate that at all. This just demonstrates how bad a UI can be, if no thought goes into it at all.

Not everything has to be visible all the time, settings can be grouped, and the user can be guided through the settings piece-by-piece, instead of just putting every option next to each other.

This does not have a GUI because making a good GUI is alot of work + the target demographic are more technical people that are able to use the CLI, so why put in all the effort?

Many of the settings are unnecessary, for example, input file format switch: I would prefer a computer to figure out this for me. And there is no need for all those "display X" switches because you can display everything at once.

The whole input format to me looks like trivial thing. Start with extension, if not look for relevant headers, if not throw it at asn1.
