In web design we often have a number of elements in a design that are the same across multiple pages and designs. Typically this might be the website navigation menu and some side bar elements. In this question I am terming these objects.
I want to have a set of common objects that I use in multiple PSDs. When one of the objects is updated then this change should automatically be reflected across all of the PSDs that reference it.
These objects are likely to just be a few PSDs sitting in a folder that are pulled into the overall page design PSDs.
How can I do this with Photoshop? Perhaps there is a better or complimentary tool out there that deals with this problem. Any suggestions welcome.
