This software is the best one I have ever seen. It's very quick to browser and incledible quicker to show pictures and zoom them.
I really would like to see photo browser graduated and full of functionalities, like video support.
Photo browser is fine as it is now. It have a simple UI navigation and a folder structure or album navigation. I really don't feel a need for anything else (to complicate) UI navigation. I certainly think that a splash (loading...) screen would be nice and just that.
As I see, things have to be easy, simple and fast for using. Photo browser have this 3 requirements. That's why it is so good.
As a conclusion, I dream to see softwares like nokia photo browser for other utilities. An example is the Nokia Music Player. That's one of the worst UI software builten for playing music. I rally dream that someday I will see a beta project for a better Music Player. Maybe using Photo Browser's UI for browsing songs.
Thanks for reading.
