"Worked for my Purposes."
Full-featured, handles certain file types that my Photoshop Elements doesn't handle.
None yet. Doesn't handle .jp2 files natively, but the plugin is easy to acquire and install. (Minor)
I just needed something to open JPEG 2000 files (.jp2). I also needed to get and install the proper plugin, and then it worked like a charm.
