Interesting feature to add would be to turn a collection of tasks to perform an outcome in a job save this a custom task marco.
In one scenario you may have something like this Setup
Job 1 (Runs Sequentially)
Task 1 - Some Action
Task 2 - Some Action
Task 3 - VisualCron Interaction - Execute Job 2 and wait till complete
Task 3 - Some Action
Job 2 (Runs all tasks as once)
Task 1 - Some Action
Task 2 - Some Action
Task 2 - Some Action
Final Result
Job 2 isn't performing actions uniquely required by Job 1 and often I am finding I have to setup additional jobs to performing the same thing multiple times for other jobs I have in visualcron. By allowing Task 3 to be saved as a collection of tasks to be executed differently to Job and not listing it as another job in the system on the main page this keeps the main dashboard cleaner and easier to follow.
How I imagine implementing this is to create a new Task type that allows you to create a new job with tasks, this Job can execute the tasks in sequential/simultaneous format independently of parent Job and also inherit Active Variables in parent task. The Final job output could be defined in one of three ways, collective output from all tasks, output of the final / specific task or Success/Fail result.
