Blank Page Icon - Create a new sketch. Edit Icon - Edit an image. Trash Icon - Delete an image. Folder Icon - Open an image. Gallery Icon - Alternate between thumbnail and list view. Preferences Icon - Change the program options. When viewing in thumbnail style tapping on an image won't highlight it, instead it will be opened. Tap on the blank page icon to create a sketch or select an image from the list/thumbnails to edit it. Have fun! When you close the window you will be presented with an option to save your sketch. If you are editing an image and choose discard when saving it, the image will revert to its last state. Tap on the preferences icon (see icon list above) in the main application to access these options: In the 'Start with' selection box you can select if you want to see a list view of images, a icon view of images, or a new sketch when you open the program up. If joypad scrolling is enabled you can move the page scroll bars around in the sketch with the joypad. If grow on scroll is enabled the sketches dimensions will get bigger as you scroll from left to right or top to bottom and vice-versa.
