I tell you why the idea page doesn't work. Because they've hidden it so damn well that most people either don't know, or forget about it. It's a hit&miss for most.
It should be more closely integrated into their website, not a hidden link in a super long hidden forum post.
Also keep in mind that the majority of ideas are not properly executed. Fullfill their 4 idea requirements, have at least 1 vote, and you've got a fair chance. Don't, and they skip it.
But yes, get effect parameters, now :D
