I'd much prefer to hide Display Text because it'd obvious that I'm displaying text :). In its place, the first line could be bolded. In addition (probably not feasible, I know), I'd love to see the name of the macro as the source, instead of just KEYBOARD MAESTRO ENGINE.
Of these two requests, removing the redundant Display Text is at the top of my list. (I know I can write a custom HTML prompt, and have done so in the past, but that's a lot more work than just picking an action from a list!)
