djvu_nav is a TUI program to edit the NAV section of .djvu file. It works by leveraging djvused with a small parser made with nom. The interface is made with ratatui and crossterm, and a bespoke treeview widget inspired by tui-rs-tree-widget.
The editor used to edit the names of the sections is hardcoded as nvim, this should probably change to be something like $EDITOR in the future.
