Points

• event callback consistency (evtObj, elm, others,...) //check other libs
• over-rideable classes (cst-ovr-elm) for label, textarea, icons, helper text, error text //check other libs
• Show state indication (filled/ empty/ error/ right / focus) + color
• Help text for *Required, error labels, text count
• if large helper text wrap (mobile/ web)
• if multiple errors show one, remaining on hover of error icon
• fonts (text - Subtitle 1 - Regular 16, Label - Caption - Regular 12)
• EXT trigger cases
• Check logging, security, performance & flexibility
