The most useful feature of this software is that you can manage your photos using it without having other programs installed (iPhoto). It's not really user-friendly but if you're proficient with computers then definitely give it try! I don't think there are many problems because all features work well enough so far. If nothing else works out right after installing it could be difficult at first; however once everything functions properly from start up to usage in general it should run just fine. Managing my photo library quickly & easily through one program instead of two or more would have been great had they allowed an option like iPhotos did back when Photos was still around.
