Show % of reviewed features for open & synthetic datasets

Description

It would be helpful to know the extent to which a dataset we feature has been reviewed by the community. We'd need a way to track when a feature has been added or rejected and some logic for whether one rejection is enough for a feature to be hidden. Once we settle on the logic though, we should have an option to sort data by this % and encourage the community to get to 100%. This is very similar to how the Tasking Manager works.

Agree, if we could get this information from somewhere it would be great to show it to users. 👍
