In Structure 3, search and filtering functionality was removed from the issue page. But sometimes we need that to rearrange structure without leaving a specific issue.

More feedback:

But with the loss of the toolbar we can no longer filter or search the structure from the issue view.

We frequently need to unpin, search then re-org the structure, and we like to do it from the issue view. At my work we are considering rolling back to 2.x to get the search/filter feature back on the issue view.
