Unlike Lyn, Unbound doesn't show everything on your computer including desktop, documents...etc.
Unbound accepts everything you wish to import, but only images. Maybe other staff too, haven't tried.
I like simplicity with very nice clean design.
There is thing that really bothers me, and the developer ignores all emails.
Looks like it is having a hard time to handle more than 11,000 images. This is what I encountered. The beachball was turning and turning.... Finally after about 3 minutes stopped.
Today I imported more images from Photos. Total became 19,000 images. Again the beachball, but this time it kept turning for much longer time and then the whole computer FROZE.
After I turned it off and on again(my keyboard is not the original mac's, but cheap one, works great), finally Unbound CRASHED. If the developer will bother to visit this page and give us some help, would be great. Otherwise Lyn will be a better option in this case, whose developer also doesn't as well.
