I am curious to know if it is possible to have a pop-up screen when a new tab loads? I want display a message to the user. They can click and X to close it.
You can’t trigger actions with tabs, so no you can’t do it exactly as you asked.
What you could have is some sort of component - perhaps a Hint component - with a message that only is shown once to each user. You just need an action on the component that sets a user specific column value somewhere, and then only show the component when that column value is empty.
That’s cool. Thanks!
