Most notifications are for non-technical end users. The language in the OoB popup notifications is full of IT jargon, something that end users do not appreciate or understand. And sometimes there's more they need to know about the update. If the tool allowed us to edit the body of the popup, our end users would be much much happier.
Design-wise, the PMP pop-ups needs improving. It looks.. cheap and like a bad 90s web-popup and is the primary reason we avoid using it.
By way of comparative example that works well for the functions it can perform: The Toast Notification solution by Martin Bengtsson looks much nicer. It feels like a Windows integrated solution and the framework is highly customisable, allowing a custom HQ image, personalisation and different buttons (such as a link to a guide housed on SharePoint). Conversely, the look and feel of PMP fonts, image and limited customisability is poor - oh and the awful black line box around the pop-up also! The defer options are ok, though not sure what happens to timings and notification if in presentation mode, screen locked or after awakening from hibernation/sleep.
Lastly since PMP can handle updates automagically as new releases hit, there may be cases where multiple pop-ups come one after the other. Scheduling an update for later would be good to have also e.g. remind me in 1 hour / 1 day / Friday.
I absolutely agree with Chris... We also need to change font, colors and style...
Yes!! And also add the ability to add custom font style and colors so that it can match corporate branding! That way users are less likely to think its some type of phishing attempt and more likely to actually pay attention to the notification!
