Automatically render progressively enhanced forms when viable (see here for why this matters)
Integrated product analytics
Custom input plugin system
Carefully apply accessibility guidelines (keyboard navigation, labeling, colors, etc.)
Maximize use of Web platform primitives (e.g. input types, autocomplete)
