Sticky Notes - Add
This is part of the Sticky note functionality of the Plug-Ins.
Selecting the Sticky Notes - Add tool draws a special Plug-In Pro "Sticky Note" field on the current page or background (whichever you're on). You can type your comments or developer notes into the sticky note field.
You can change many sticky note properties by changing the Sticky Note style in the Styles - Field screen accessed from the Objects palette.
