The merging capability does not go far enough. I'd like an option when I merge ideas to 'hide' the merged idea from the portal, counts, and from list views. This would then provide a better count of outstanding ideas by status. Without this ability to hide 'mergee ideas' , every list I do has to have the merged status filter.
The merged idea filter also does not go far enough. If I want to see all un-merged ideas with ideas who have been merged (along with their ideas which have been merged into it), I have to combine run two reports and then combine them into a single report.
