Inspired by similar redirects on php.net, I implemented a redirect on Flex.org that gives you easy access to Flex Package Documentation. Just type flex.org/fullpackagename into your browser and it will redirect you to the official Adobe LiveDocs page for that package. For example, flex.org/mx.controls will take you to the mx.controls package documentation.

Any plans to support classes too? For example, attempting flex.org/mx.controls.Alert attempts to load an Alert package rather than the Alert class. Given "official" standards, you should be able to make this distinction simply through capitalization.
This is great!
Do you think you will extend this functionality to accept individual classes as well?
Hmm... Two requests for classes in an hour. Seems like a popular request. I'll have a look at the naming schema and try and come up with something tomorrow.

Nice and handy improvement, but indeed:
Having this feature extended to support classes would be really great!
That feature has been added. See my blog post from today.
Thanks for the suggestion!

Cool thing, why I discovered it so late? BTW, it seems this redirect feature stopped working.
I mean that http://flex.org/mx.controls says "404 - Not found". As far as I know, you can implement it back in Drupal with URL aliases module.
