Have you looked for something in the Ideas section only to find that 7 people have already registered an Idea but they are all just slightly different (Add this field, let us choose what fields...)
Can we get a function in the Ideas that allows people searching for Ideas to flag already registered Ideas as similar, Ideas that are similar enough to be merged into one broader idea are done so and the votes for both (or multiple) are added together pushing the Idea further up the priority list.
