Bookwyrm is slowly taking form. The index menu has seen some improvement: https://asciinema.org/a/0NAQk2ws62XRLy7Q7H6wkFCDI
The part were the index menu is minimized is where I open another (unfinished) screen. In this screen, the program will fetch some item details from Open Library and print it out in a nice format. Hopefully we'll end up fetching info about the right item. But as long as we get an ISBN β€” which most sources do β€” it shouldn't be a problem.

Soon I can get dirty with writing Python scripts, but before that I'll need to find a way to gently interrupt a std::thread. Unfortunately this isn't something C++ allows natively. The reason being that we don't want to wait for the source scripts to end before we can terminate the program. The easiest way of doing this would probably be to poll program-terminating-or-not status within the scripts themselves, but I'd like to require as little boiler-plate as possible.
