Currently, there is a new option that allows us to put a specific date to interrupt the workflow like a "day-off" when we don't want our contacts to receive our emails > This is not really understandable that it only interrupts the workflow for a specific day, I thought that it would interrupt the workflow forever, so that's the first thing to emphasize that is a bit confusing.
From there, I am coming up with my second suggestion: getting the possibility to stop the workflow forever so that I don't have to come back and hitting "pause" manually.
