In an action, when a field is occupied by a variable, it would be nice if after lingering the cursor over said variable for slightly less than a second, a popup appeared with both the var's value (in real time) and its description (if there's any).
Saying this because sometimes we don't need to set the debug option on to see all vars, nor do we want to move back and forth between State and Variables tabs to quickly check on the value on a var.
