Tadak also offers these advanced features:
- Color-coded Jamo (Initial, Medial, and Final Consonants): Even on complex three-set layouts, the clear color coding helps you easily distinguish which keys input initial or final consonants.
- Hanja Conversion: Convert text into Hanja character-by-character or word-by-word. You can also convert Hangul consonants into special symbols.
- Old Hangul Input: Type Middle and Early Modern Korean seamlessly. (*Characters may not render properly if your device environment does not fully support Old Hangul display.)
- Import Custom Layouts: Load custom keyboard data files to use your own personalized layouts. This feature is adapted from the core mechanics of the Nalgaeset Hangul Input Method.

Keyboard Features

Keyboard UI
- Fixed an issue where the keyboard area would briefly expand for one or two frames when the keyboard appeared.
