thats a very good idea. It should randomly go through them after sets amount of time.
Having an editor settings option would also be good for this to turn off.
Also smaller monitors my struggle with it.
Another way of displaying is that we could make it smaller and click on an icon to display the rest. The icon could highlight when a new tip is showing.
They would be even better if we took them from an online file, because we could make them show notifications.
Great idea

Visual Studio does it.
We can call the option: tips and notifcations
