Oh god yes. That would open up hundreds of new things you could do.
Also, I think there should be a "always" input event that does the event over and over as long as it is enabled.(delay would be how much time between events)
You can do this by repeatedly sending a relay or projectile at a brick, but its ineffective and stops you from using relays or projectiles for other stuff in that brick.
Speaking of relays, what about named relays? I.e when Relay A hits the brick, stuff happens, but when Relay B hits the brick, other kinds of stuff happens.
At laremere, of course, but can you check what someone wrote on print bricks with turning on and off events? Can you see what number a counter is on?
