Currently editors can edit items that are connected to the CMS without going into the Collection. They can edit directly on the page where the CMS item displays, which can cause all manner of problems.

Adding a visual way for editors to see which items are connected to the CMS (and which are not) would potentially solve this problem.

I've tried to add tooltips to warn editors they must go to the collection in order to make changes, using Toolstipster, but can't get it to work only in editor view. The tooltips are visible to all, and not visible when in editor mode.
