autocompleter which isn't (a suggest box) |

- don't just on first option on appear |
| 10 |
- removed fade-in/out effect |
| 11 |
- added configurable width (content width? centered?) |
| 12 |
- add icon which means suggest |

hopefully, this implementation won't break (much) when I update |

prototype next time :-) |
