RibbonDiff — Support

Open Settings
In the menu bar choose RibbonDiff → Settings… (shortcut: ⌘,).

What you can adjust

• General: toggle line numbers (per pane), enable/disable word wrap, or reset everything back to defaults.
• Appearance: tweak diff highlight colors (Added/Removed/Modified) and the center connector (“ribbon”) color.
• Backgrounds: choose System backgrounds (follows Light/Dark Mode) or switch to Custom colors.
• Themes: switch between built‑in themes or your own saved themes.

Import a theme (JSON)
Go to Settings → Theme, click Import Theme…, then select a .json file. Imported themes appear under User Themes.

Export a theme (JSON)
Go to Settings → Theme, click Export Theme…, give it a name, then choose where to save the .json file.

Tip: If you imported a theme but don’t see it in the list, close and reopen Settings and check the Theme section again.

Text looks out of sync after a large paste
Try clicking into the pane and scrolling once, or toggle Word Wrap off/on to refresh layout.

Performance with very large text
Very large comparisons may take a moment to compute. If it feels slow, try comparing smaller sections or splitting the input.

Theme import/export issues
Make sure the file is valid JSON. If you imported a theme but don’t see it, reopen Settings and check the Theme menu.
