Hello,
Have you already been annoyed by the fact that you saw some quick notifcations on the top right corner of the screen (from a EKL script for example), but you didn't have time to read them completely because "Local save successful" appeared immediately after, or something else? 
Have you already been annoyed by the fact that you have to run the whole script again, just to check the notifications that you missed? Furthermore if the script takes long?
Long time ago I have. But not anymore, because a colleague once showed me this tip that I am sharing with you now. Simple but you just have to think about it.
