App Island

Clone an app into a separate space, freeze it while you are not using it, and remove it when you are done. This is a simulation of how Island-style apps keep a second copy of your apps apart from the first.

App Island

How this app works

The whole app is one JavaScript object plus a few small functions, the same ideas you used in Python with dictionaries and functions.

const island = {
  notes: { frozen: false },
  chat:  { frozen: true }
};

function cloneApp(id) {
  island[id] = { frozen: false };
  render();
}

function toggleFreeze(id) {
  island[id].frozen = !island[id].frozen;
  render();
}

function removeApp(id) {
  delete island[id];
  render();
}

island is like a Python dictionary. Each key is an app, each value says if it is frozen.
render() redraws the screen from that data, so the screen always matches the object.
Your changes are saved in the browser, so the apps stay after you close the page.
