I've there's very little navigation available when viewing an Idea Exchange's post. It would be nice to see the post name up in the breadcrumb (below the workfront banner) and a hyperlink to the post on the same page.
Copying the current url when viewing a post may not be suitable as it could have been a link to a specific comment and not the base post.
I did notice a permalink option is available on comments, but not the post.
