A good feature is the Watch Folder... any change you make in the folder, will be changed in MPI...

Other good feature is differents words search. For example:

"Soccer game between Botafogo and Flamengo"

If I type "Soccer" and "Botafogo" ("Soccer Botafogo") the software don't find anything, so this could be improved. Typing this two words I can find my photo!

This is only an idea.

Thanks!
