Lightroom really needs an easier way to put together a collection of images that are spread across multiple Catalogs.  I tend to create a new catalog at the beginning of each calendar year, which has left me with individual catalogs for 2006, ’07, ’08, ’09, and ’10.

That works well enough when dealing with individual shoots (each catalog is well-organized into Collections), but putting together a portfolio that contains images from each year is downright tedious.  I have to select the shots from one catalog, export them, then import them into a new catalog.  Simply creating a new catalog and using the “Import From Catalog…” feature is imperfect at best, especially due to how much it lags and how difficult it becomes when there are half a dozen virtual copies of the same image.  I’d love to have an easy way to put together a Lightroom-created web gallery that pulled from multiple catalogs seamlessly.
