This app is very good; somewhat slower in indexing large folders than Extensis Portfolio, but the difference in price makes it worth the time. Unfortunately, though it is all in all a great organizer for pictures, it has shortcomings that make it unsuitable for the management of scholarly media collections. For that it would need to have:
-The ability to add custom columns, to differentiate author/title of the picture form author/title of the object pictured, and to add other info;
-Nested categories, so that we could have, for example, a category for catholic art within a broader religious art;
-The ability to assign date ranges fo each work (beginning-completion) and to order by these ranges.
Until we can have such features, Portfolio is the only program flexible enough to come close to meeting scholars' needs.
