Lets suppose I have 5 Jobs, which are chained together. (When Job #1 ends, Job #2 starts, etc).
If Job #1 has to be modified, or worse, disabled, then Jobs #2-#5 will either run at different times, or worse, not run again. By the time you get a RPO warning, it may be too late.
To mitigate this, I think a warning should be displayed when modifying/disabling Jobs which have others that depend on them.
"This modification will impact Job #2's Schedule, since it is chained to Job #1. Apply Changes?". Or something of the sort.
Let me know what you think. I know it would have helped me a couple of times

Thanks!
