A) There is no option to search WITHIN Idea Exchange, only the whole community. So we can't find a well expected suggestion to vote on it.

B) Stupidly, a million votes on a suggestion/complaint on the main forum, doesn’t compel QB, it must be on Idea Exchange.

As a temporary workaround, when posting on Idea Exchange, put a link to the post on the thread of that topic in the main forum.
