Version 1.2 of the Notifications Plus add-on brings with it a few bug fixes related to notifications getting stuck on screen and instant notifications.
I have also added in a new option to allow you to select which point types should give a notification! Make sure you setup your point types first then select all the types that you want users to see and you are done!
