I love this software because it allows me to organize my pictures in folders, gives information about each picture (like date taken), makes automatic backups of all files saved by PM so if there are any problems/losses they will be restored from backup automatically! It's very fast compared other similar programs like Picasa or Lightroom - no lag at work when making selections etc; also easy for beginners as well experienced users can use them without getting frustrated which sometimes happens using more complex softwares such as Photoshop CS6+LightRoom CC3+.
Sometimes saving an edited photo does not happen immediately after clicking'save' button but only few seconds later while waiting time increases until finally giving up trying again & loosing original file before being able too save edit version ; still though saves frequently unlike some versions where editing takes ages even just selecting one part of pic then going back into main.
