I have been silent for a while, publishing progress reports and demos is not as fun as programming and debugging. I released the latest update of cardano.el, which now uses an SQLite database to manage state. It is a massive increase in complexity, but it enables wallet like features. It keeps track of key files, script files and manages addresses. More over it now has an optional integration to Cardano-Wallet, the backend for Daedalus. That solves managing an HD wallet and directly spending. For everything else of more complex nature you can go back to using the editor.
I uploaded the new demos on the Ars magna YouTube channel and here they are in immediate succession.
