This PR is way too big to be reviewed properly.
I'm not sure every settings are necessary (especially from the start).
And I also have issues with the fact that every Theme from Ace is included.

[cloverhearts]

Thank you for feedback @corneadoug .
I can possible divide to this pr.
and I have a question.

I also have issues with the fact that every Theme from Ace is included.

Can you give me an explanation why that is a problem?
If you have a problem, I need to clear a part of the theme changes.
a very easy fix.
I thought that people would want to coding in a theme familiar to them.

Once again thank you for your message.

[corneadoug]

@cloverhearts it would be nice to divide it in multiple PRs and commits.
For the theme, I'm not against them wanting to change it, however in this case crowding the build by importing all the Ace theme inside the build, even though 70% of them will probably not be used.

[cloverhearts]

I removed the feature to change the theme.
It will also split into a new PR.

The indention does not look aligned with the parent "main" above. Previous one was.

Also, adding such changes to PR that implements new functions makes code review task harder (and slower) - now everyone who reads this need to think, if this changes are part of the new feature or not.

[cloverhearts]

@bzz
I will fix.

[bzz]

I agree with @corneadoug that this is a big change to review.

One more thing - @cloverhearts can you please add some tests for this feature?
See AuthenticationIT.java for an example of Integration Test

How can I use this feature?
Though I've installed latest build version, I could not find "Editor Configuration menu" anywhere.

@hyonaldo
Sorry,
We can not support this feature on zeppelin.
I do not care for this feature into master.
It also differs from the current source in many ways.
Re-implementation is required.
I have no plans to reimplement this until now.
Perhaps, if you want this feature.
You can create an issue in our jira. (https://issues.apache.org/jira/browse/ZEPPELIN)
Sorry, again.
