What can you do with all this? Build your own application. Use what’s given and also build your own new elements based on these. Everything you will find in this .psd can be modified and re-used. Scale panels/buttons/inputs up and down and change colors.
P.S.: only one (1) font is used: Arial (pretty standard ha? You must have it in your system.)
