Zhong Wang, Right, Folder support would be quite useful. Thanks for the opinion. Hope i can finish the work pr-190 <https://github.com/apache/incubator-zeppelin/pull/190>.
Sourav, Regarding concurrent running, Zeppelin doesn't have limitation of run paragraph/query concurrently. Interpreter can implement it's own scheduling policy. For example, SparkSQL interpreter and ShellInterpreter can already run paragraph/query concurrently. SparkInterpreter is implemented with FIFO scheduler considering nature of scala compiler. That's why user can not run multiple paragraph concurrently when they work with SparkInterpreter. But as Zhong Wang mentioned, pr-703 enables each notebook will have separate scala compiler so paragraphs run concurrently, while they're in different notebooks. Thanks for the feedback!
