This is a wonderful app if all you want is take a quick look at your pictures.

It shows my pictures fast, really fast. Ok, super fast. Period.

Some of the former posts point out, that there is freeware that can replace myPhotos:
It's the old adage "You get what you paid for." Personally I pay attention how I spend my money. Since I am a developer by myself, I know how much time it takes to create something like myPhotos and I LOVE to show my appreciation to that guy by paying for the app once it is released.
At the current beta state it is fair to give feedback on the features, but unfair to complain a future pricing.
