It's possible to make modifications, undo and redo actions, search and replace strings of characters, and jump to a specific offset in decimal or hexadecimal form.
In addition, you can hide the toolbar and status bar to make the main window look less cluttered, as well as view file properties, namely the location, size in bytes, original size, and whether it's modified or read only.
Regarding program settings, you can allow drag-and-drop editing and scroll tracking, show all characters, instruct Cygnus Hex Editor Free Edition to create a new file on startup, and modify the default undo and redo levels. The file structure modifications can be overwritten to the original file or saved to a new one by establishing the output directory and file name.
