GLUON Linkster for Mac

From GLUON:

Linkster lets you easily link or unlink any text selection or even entire XPress documents. How many times have you gone to duplicate or copy a box only to get a warning that this box has linkages which can't be duplicated? Linkster solves this problem instantly by unlinking the box, leaving all the text exactly the same. Linkster gives you a range of options for unlinking as many boxes at a time. Linkster can have 100 boxes of linked text all separated out in a matter of seconds instead you suffering through hours and hours of cut, unlink and paste!
