There are a lot of feature requests and bug reports there that are tagged as "Planned" or "Under Review" here in this Canny. However, it does not make any sense to keep those as planned if they have not been implemented since several years.
A better approach would be to avoid using this tag if the requests are not actually planned, and also to remove older tags when plans and priority have changed.
Otherwise, trust is lost and this place and the users feel neglected.
