I almost posted this to the Off-Topic forum, because it may be "technically" off-topic. But I think Mario deserves unique praise for his development of IMatch over so many years... It is regrettable when no one pauses to simply praise the intelligence, creativeness, and ingenuity of a software developer who make our lives and jobs less stressful and more enjoyable.
IMatch has been critically useful to me, on a daily basis, for nearly ten years. I am not a pro photographer, but like many amateurs, I take many photos, and IMatch has provided both an elegant and intelligent system to store and recall those memories.
On a more important note, my wife had a very difficult lawsuit against an employer 10 years ago, and I discovered (by accident) that IMatch was also a perfect document manager for classifying scanned records. Imatch was a godsend, and, unlike the lawyers, I always trusted IMatch's capability : ) Three years later I was dealing with another legal case- and IMatch was there to help.
I think IMatch stands apart (and above) as a pro-level, multi-format DAM... which somehow still remains end-user friendly. Imatch is a very unique and fascinating piece of software that is often just fun to explore.
Thank you Mario!
