Yes its a great Feature....
I tend to break down all my events into systems
so for each system in the game ..like
player controls
enemy ai
music systems
level generation
HUD events
Camera controls
etc
they all go on their own event sheet
it makes it soooo much easier to read and find where problems are..when debugging because then the debugger tells you exactly where the bug is happy joy
Build robust systems from well planned events and you have epic WIN
