Github user 1ambda commented on the issue: https://github.com/apache/zeppelin/pull/2356 @Leemoonsoo I did some experiments to revert the original layout while keeping highlights. But I think it takes a time to fix. So here are few options. (A) revert 2356 and then reimplement the highlighting line feature considering original layout later. (B) keep current layout and refine designs so that new layout goes along with other components. And #2386 is for `(B)` while fixing some bugs. Could you consider `B` as well?
