About the gesture input:
- The home brew "swipe" algorithm is very young, so don't expect it works exactly like other swipe keyboards. I want to keep the algorithm simple and small.

Tips:
- For long words, try not to swipe the whole word (You may append gesture).
- Make sharp corner for better prediction.

a.k.a The next generation of Multiling Keyboard, Tablet keyboard, DIY keyboard, emoji keyboard, Floating keyboard.(maybe conflict with Paranoid)
