In this case I'm looking at Send event set to Game Object FSM.
I create a new Event from the Events tab, then make it global.
I go back to the action, target a GO, then its FSM.
The action properly sees the targeted FSM's events but does not see the one in the FSM I am editing.
This, I think, shouldn't be happening.
But as all FSMs, both in this FSM and targeted FSM would be visible, then perhaps a separation would be necessary, like a gray line and perhaps even written in bold the descriptors of both categories: This FSM and Target FSM.
