Sort of a downside to that tool is that it requires a web server (wordpress) to run. It would require a local instance of one if there's to be a cached version to run from when there's no connection available.
Hence my proposal a while back, to have the installer widget/window run "webkit" and use "site.js".

They have also already implemented E23.

We look to be losing momentum i.e others getting ideas done we've already opted for.
