Currently with just a click on the vote button users are allowed to vote on an idea without providing a proper explanation as to why they think the idea is worth the vote.
We are noticing users just rallying behind a submitted idea without valid reasons just to get the idea prioritized above others. And this is causing pain to PMs during ideas review process and derailing prioritization. So it would help to let users provide a simple explanation as to why they are voting for an idea. It will be helpful if we can have this as an option on the Ideas portal settings.
