Pop Up Dialog

This feature request is to discuss the possibility of having a new workflow action called “Send Dialog to User”.

I know that if something happens that requires notifying a specific user, we have a few options available to us. These being @mentioning a user, sending them an email, and hopefully one day, sending them a message in Tape. However, it would be awesome if there was a workflow action that would force a pop up window to appear for that user informing them of something. It could be exactly the same as an external link workflow (supply your own text or HTML) and also would be great if the dialog would appear until it was cleared by the user. Meaning that if they were not on Tape at the time, the next time they login or visit their browser, any open dialogs would appear and would have to be cleared before they disappeared.
