Working with files/Undo and Redo:
The upper horizontal toolbar is located at the top left of the main window. It contains 5 icons:
1. New image (Standalone only)
-------------------------------------------
This icon looks like a sheet of paper. After you press it, a new dialog will appear where you can select the size and background color of an image. Also, you can open this window by pressing Ctrl+N on your keyboard.
2. Open an image file (Standalone only)
------------------------------------------------
This icon looks like an open folder. When you click on it, you will see the Open dialog, where you can find and choose the file you wish to load. You can also open this window, by pressing Ctrl+O on your keyboard.
3. Save results to a file (Standalone only)
-------------------------------------------------
The icon looks like a hard disk drive with pointer. After you click it, the Save dialog will appear, prompting you to save the image data into a file. Enter a name for your image and press the 'Save' button. Choose another path if you wish to save new image to another folder. If you want to save a loaded image, press Save and confirm this. In this case the opened file will be overwritten. If you don't want to overwrite the file, you can change a file name and the image data will be written to a new file.
Tip: Also you can create a new file with no changing a file name. Simply choose another folder to save a file with the same name.
You can open the 'Save' dialog, by pressing Ctrl+S on your keyboard. Also, you can choose a file format when saving your image (.bmp, .jpg, .jpeg, .png.)

5. Redo
