From StartBox Docs
StartBox comes with an incredibly easy-to-use, modular settings page. For users, this means a quick and painless setup, for developers this means an incredible new level of control and flexibility for your themes.
Adding an Options Panel
You can use the sb_register_settings() function to add your own options panel.
Removing an Options Panel
The Options API derives its real power from your ability to Create Options. There are loads of pre-defined option types at your disposal, ranging from an AJAX uploader to simple text boxes.
Interacting With Your Options
Because the options are all stored to a single array, StartBox has a few helper functions to make it easy for you interact with that data.
