Items in use
The Items in use actions shows a library containing all the items which are in use (these items have an active itemlock on them).
The column Since shows since how long ago the itemlock has been set on the content item. The column In use by shows which user does have the item in use.
You can order the list on any of the columns by clicking on the column header. Use the filters on the right if you're looking for a specific content item which is in use by a specific person or which have a specific person as author.
The itemlock(s), when needed, can be removed by selecting one or more items and clicking the Release button. Notice that you won't be asked for confirmation, the itemlock(s) will be removed immediately when you click the Release button.
