    @zjffdu 
    Thank you for your best advice!! :)
    and Sorry, I missing the description.
    actually, i made that on codebase. (dynamic form is removed.)
    
    In fact, this feature has a dependency on Spark.
    However, it is designed to be easily re-implemented in other interpreters.
    There are also advantages.
    
    Since calls can be made at any time in the code, we can use them together 
during analysis or in combination with external libraries.
    (DAG is the same)
    
    By default, this is not a complete implementation of the workflow.
    However, I think this feature provides the basic user environment for the 
user to use freely.
    
    
    ```
    if (z.getZeppelinJobStatus("execute note id", "execute paragraph 
id").getJobStatus().isFinished() == true)
    { z.run("execute note id", "execute paragraph id") }
    ```
    or
    ```
    val result = z.runSync("execute note id", "execute paragraph id")
    if (result.isFinished == true)
    { println("job is done") }
    ```
    or
    ```
    z.run("execute note id", "execute paragraph id")
    while (z.getZeppelinJobStatus("execute note id", "execute paragraph 
id").getJobStatus().isRunning)
    { // loop }
    println("next job or done.");
    ```
