Diff highlighting — added lines in green, removed lines in red, plus word-level diffs for exact changes.
Merge support — apply changes from one panel to the other with arrow buttons in the middle gutter.
Undo / Redo — full undo and redo for every merge operation.
Fullscreen mode — expand the comparison area to fill the screen.
Options — ignore case, ignore whitespace, wrap long lines, jump between changes with prev/next, swap panels, upload text files.
