Command-Line Interface

[jgarte]

Hi, have you thought of making a command line interface similar to the below Perl app?

Hi, thank you for the issue,

It could indeed be done as well as all the other options using some metaprogramming i guess like --general_x_start, --general_open_colors_root. I've never really thought about the design though

I'll look at it when i got time. A pull request will be appreciated for this feature if you want to try

The Perl app looks good!

In Python, Rich library (https://raw.githubusercontent.com/textualize/rich/master/imgs/features.png ) might help.
