Wish for JSON extensions
Extensions that help us to build JSON driven .html pages to be used in mobile apps - PHP isn't allowed and therefore rejected by Apple. Extensions that would allow us to both retrieve data and insert data in to a database. So, if eCart and DataBridge could allow us to do this, that would be most advantageous as we'd then be able to PhoneGap a mobile site in to an app.
A tool for SASS or LESS CSS would also be good.
