I have thought about that. I will do if there's demand since I would really love for people to be actually using this and right now only developers can use it.

Will require a bit of simple front end work. For example, translating an epub really needs to involve the user (which is currently available in the terminal) since it's very difficult to automatically translate names.

For example, "April" can be a month, a town name or a person's name. It needs flipping if it's a name, but not otherwise. Even context sometimes doesn't help: "We were worried about April."
