Keyboard Maestro 7 or 8 needs try catch blocks

It would help me so much if there were try/catch blocks in flow control.

Giving actual use cases would be more helpful.

Some sort of flow control that catches failures is likely to be implemented eventually, although exactly what form it takes is uncertain. Probably just a Try action that looks like the Group action and that propagates the %ActionResult% from any failing action within it. But the implementation for that is far from certain.
