Comments in actions, 'Wait for previous actions to complete' & more.
No. The opposite. This refers to actions, not conditions. Un-picking, not picking. Pick all just muddies the water.
"Pick all" does unpick everything, reverting state to as if no events had been run. An action wouldn't work any differently.
You know, "Pick all" never worked for me.
Just spent some time, and it turns out additional filtering needs to be in a subevent. Might want some documentation there. Still think an action would be nice.
