I want the button back. I have many nations for which I do only specific issues from time to time and dismiss the rest. If someone doesn't want to use that button they just don't need to click it, simple as that. It's not like you're forced to click it....
So please add it for the people who want to use it, and the people who think it's not right to use it can just avoid clicking it... maybe add a 2nd page where one's asked if they want to REALLY dismiss them all, to avoid accidents.
