In case you didn't notice, Agile UI + Data bundle can now be downloaded from the site with just a single click.
Additionally if you are running a Mac, I have included a very simple app which will run a PHP and open a browser window. You don't have to install anything at all. For Windows users, simply drag the folder into your favourite LAMP application's web-root.
Please let me know if the new download and installation process works well for you.
For those who want to help me make it even better - here is the bundle builder repository: https://github.com/atk4/agiletoolkit-bundle
