First, here (in Ideas) is any type of pagination missing, am I right?
Second, some of ideas I see, I understand them, but can't (don't want to) rate them because the topic doesn't interest me, it's not related with my interests... So I want to ignore it, but there is no button for this. It's still and forever a part of "You haven't rated" list.
Third, what about an even another button "I don't understand what you mind!"? :-)
