Version 1.1 is coming along nicely.  1.1 has albums to arrange your favorites, you can do a slideshow of favorites, and you can import / export an album of favorites (instead of importing / exporting individual images).  I'm going to try to make the favorites screen look a little nicer though.  Right now, I use a simple table format with a small version of the image and the date it was added (one of each per line in the table).  I'm going to change it to be a grid of images instead (I don't know why I thought the date added was interesting in the first place, but I was wrong and I'm going to remove it).  I'll be soliciting beta testers soon (maybe the end of this week or sometime next week).
