FAQ
- When use line-level vs character-level diff?
- Line diff suits configs and logs. Character diff highlights intra-line edits—better for sentences or small string tweaks.
- Side-by-side vs inline view?
- Side-by-side shows old and new panels; inline merges changes on one line with colored insert/delete markers for narrow screens.
- Are trailing spaces ignored?
- Comparison is literal, so trailing whitespace counts as a change. Normalize text first if you want to ignore spacing.
