enh: do we want a slight different interface that allows a user to select what they want to customize?

[lwasser]

i also think a lot of the distinction between 'minimal' and 'custom' mode can be alleviated with a slightly different interface... like they could actually be the same mode if instead of entirely linear series of questions there was some checkbox TUI interface after the first initial question that was like

Which of these would you like to customize? 
Select with space, continue with enter

[ ] VCS
[ ] packaging backend
[ ] typing
[ ] ....

and so then in 'minimal' mode you just don't select anything and press enter, same number of keystrokes, but you also get a sense of what is possible to customize. then if you do want to customize some values but not all of them, you have that ability too.

it looks like copier supports this with multiselect
