Right now I am utilizing Javascript, CSS3, HTML 5, Ajax through Jquery, Highcharts, and Perl/cgi for database calls (custom), Python was one route i was going for the Google Analytics calls.
What i think everyone wants first will be the barebones framework. I am making the squares draggable, resizeable, and will make it a responsive for mobile and tablets.
The next thing will be to make the Google Analytics scripts available. Now I love perl, but i figure some people would like a php/javascript version. Once i get the perl calls done, i will integrate a php/javascript/ajax version.
I'll add generic perl and jquery bots to help people map it to their custom 3rd party logins, etc.
One thing that is important will be the ability to read rss, xml, and json files. That should solve 70% of most people's customization problems.
I'm pretty excited, so I am looking to give this a fast turn around time.
