I found it mildly annoying that the notifications are listed in descending chronological order (i.e. that the most recent ones are at the top). This makes no difference where there are only a few (up to 8?) notifications, but if there there are more, older messages get pushed down unfairly.
Today, this essentially meant that whoever PMed me first was the last to see a reply because the notifications of their PMs kept on getting pushed down to the bottom.
At the very least, I'd like to see an option to be able to reverse the order of the notifications. Shouldn't be too difficult to implement, right?
Thanks for looking!
