There are already wishlist items for filtering in columns on search results, but not for the pages "Where Used" & "Tags".
It's easier and more efficient to allow filtering on the columns in these specific pages instead of having to generate a report with the Tag/Doc-references.
I'm pleased to announce that filtering on related assets and related documents is available in Cloud Explorer. On the related assets or related documents page you expand to full screen, and in full screen mode you have the assets or documents filter available.
