It shouldn’t be too hard to add a new option which would always display the notification popup. Of course, it can’t be exactly like the old popup panel for reasons already discussed but may well be useful as a reminder feature.
Let’s say that if you’d be interested in this feature, like this comment. If you’re interested in helping to develop it, even better - in which case please also post a further reply.
PS: This way of gathering your feedback is a bit experimental so I might change it at some point but lets try it this way for now at least.
