As more sites move away from the everything-free-and-available-forever model, it's probably best not to be reliant on github (or any other site) to host everything forever
libraries & auto-update should be moved to a self-hosted server on a domain (ncplanner.net?), with checksums, perhaps using github as a backup if the server goes down
In case library downloading fails, instructions should be printed on how to find & download the libraries manually
