The truly great innovation of WP is plugins. They let content developers concentrate on what they do best. WP App Studio allows system analysts to design plugins that work, without endless months of coding. Basically, if you can imagine it, you can build it with WP App Studio.
You want a custom application to track workflow for your small manufacturing business? Yeah, it can do that. Need to monitor habitat restoration activities for 2,000 acre wildlife preserve? No problem. Create a sophisticated political opposition research? Piece of cake. WP is a database driven software development environment for web development. WP App Studio is the first plugin I have seen that gets that very basic concept and so fully exploits its strength.
The tool is very powerful, so it takes time to learn how to exploit all that power. Once mastered, this toolset dramatically speeds up web development. It can easily reduce time to launch by a factor or four times or more. Basically, you jump from design pretty much directly to testing.
So, where is the fifth star?? As powerful as this toolset is, the documentation, training and customer support just do not measure up. If eMarketDesign gets those things right, there is no telling how much WP App Studio could change the Internet. If that sounds like hyperbole, it's not.
