New CP/Form Object Layer

What's it all about?

• Builds Control Panel forms with a structured, object-oriented API
• Replaces hand-coded Shared Form View arrays with chainable form objects
• Organizes complex settings screens into groups, field sets, and fields
• Supports consistent CP layouts as sections or tabs
• Reuses existing Shared Form View inputs, with simplified Grid/Table and Filepicker support
• Reduces boilerplate for add-on settings and custom CP forms
