Hey there! I'm currently working on a CLI tool to deploy WordPress apps to DigitalOcean. Check it out! It's free and open source.
Here’s the video of my session about the Settings API in WordPress from WordCamp Sofia 2012. You can find the slides and notes/transcript in a post I published earlier: The WordPress Settings API.
If you’re interested in making the Settings API better and less painful to use, please chime in to the discussion on this core ticket: #18285. Have fun!
