Our website provided a free download of PowerNotes 1.0 for Mac. PowerNotes for Mac lies within Design & Photo Tools, more precisely General. This Mac application was originally created by QSystems.
From the developer:
PowerNotes is a plugin for Adobe InDesign that allows you to perform complex instructions on a document. You will be able to create these instructions combining text and freehand drawings in a special layer whose elements can only be seen in the context of Adobe InDesign.
Using PowerNotes you no longer need to coordinate with other people. The need to explain complex things or accompany InDesign work with lots of prints or other files disappears.
