Ever had lots of content nodes that you have to manually delete. This package simply adds a right click context menu to the Content area and allows you to filter by document type and delete in bulk your unwanted content nodes.
Should work on 4.5x onwards through to 4.7.2 - only a dll and aspx file to upload and not using anything those versions do not have. Does not support less than 4.5.2 though i'm afraid as one of the api calls only came in on that version.
4.8 wise, not sure - not used it at all yet so no time to test, let me know so I can update accordingly.
