Add an option to cancel an occurrence currently queued to run without it removing, or completing, the original schedule. Not sure if this is by design or a bug but when you cancel a workflow that's in queue, it sets the scheduled workflow to "Completed" even though you just wanted to stop that occurrence and still keep the workflow schedule “Active”.
Also, adding an option to PAUSE a scheduled module. This is useful when you need to temporarily suspend a workflow from running, but save the hassle of re-configuring the schedule when you want to turn it back on.
