Widget API for Developers
Have you considered allowing developers to create Widgets as plugins? There could even eventually be a whole marketplace like the Wordpress plugins, Magento Extensions, and SugarCRM Extensions where plugin developers make 100's of thousands a year on popular useful plugins.
I can understand the desire to limit this to prevent "junk code" from slowing the app down and such but perhaps a system could be put in place to require a standard is met similar to the Apple iOS app store submission process also the SugarCRM module loader actually scans all the PHP files in a SugarCRM extensions and looks for blacklisted items in the code before approving the extension for public use.
I realize such a huge feature would be down the line but I am just bringing up the idea to see where you stand on it?
