I don't think this goes far enough! Make the actually app store be the same file itself. so it's a living application and the file is constantly updated to how you use it. Copy it around, and you carry your data wiht you as well.
Let's go deeper. it's a webserver app + the server code + application code + db, so pocketbase++ where it's also the deployment target.
Then combine it with APE liek system, and the same file loads and stores things on every platform. evil laugh
Very cool hacking! My hats off to the author.
