Update on an installer or webapp

Have we got a way to run this offline yet?
I want to make a UI and add a kidpix feel to it.
Do I do that with a chrome plugin to add my js and css files?

No files, tests, or entry points are named. First determine whether offline use, a standalone installer, or browser-based UI customization is in scope, then identify the relevant application entry points; done should include an agreed offline approach and a clear plan for adding the proposed UI and styling.
