@Leemoonsoo Thanks for review.
- Then we need to close the configuration panel after saving. I will update
it.
- You have to use echo spell provided by zeppelin (`examples/`). Published
echo spell doesn't have repeat implementation since spell config feature is not
merged. (https://github.com/1ambda/zeppelin-echo-spell/blob/master/index.js)
- Regarding to version, I will check again.
