Mentioned in #4.
Sometimes it could be handy to make Demlo's process more interactive.
A script could ask the user to enter a value with
func input(prompt string) string
.
Example: when a disc number is found, ask the user if we should ignore it for the current album or not.
Some input functions could be recurring (booleans, number queries). Add input_bool
and input_number
?
