Application Development docs or tuts?

Hi. I'm really anxious to get my hands dirty with application development, but there still seems to be a slight lack of documentation or tutorials. I have also looked into plugin development, and there is already a pretty nice piece of introductory documentation ( http://community.invisionpower.com/4docs/advanced-usage/development/plugins-r71/ ) and an awesome tutorial  ( http://community.invisionpower.com/4docs/advanced-usage/development/plugins-an-example-r72/ ) to get you started. 

Is there anything out there that would help me? Will there be more documentation/tutorials anytime soon?
