It's a suggestion, but really does bug me! (Pun Intended)
I click on my sprite to add an action and click "Which Animation of 'Sprite1' is playing?"
And then you enter one to dertermine it for example
"Sprite1:If 'hello' Animation is Playing"
well it'd be so awesome if I could add multiple parameters to determine so that the event occurs if any of the following are listed, for example:
"Sprite1:If 'hello' or 'hi' or 'hey' Animation is Playing"
OR
"Sprite1:If 'hello', 'hi', 'hey' Animation is Playing" (comma meaning "OR")
