Are you suggesting users with no programming experience can simply add the flags they need to a terminal application but would be unable to do the same with a GUI because the GUI is the barrier? Not the logic and that the program will do with the flag, but the GUI is the barrier?
What are you saying?
What? Do you understand what I’m asking? Do you understand what you’re suggesting?
So googling how to do someone, copy/pasting command is better than finding it in GUI? How high are you?
Again a solved problem, just make a decent GUI for your application.
