About ThemeWatch: Compare Theme Code

Finally understand what's happening with your store's theme code without being a developer. Compare any two themes instantly and see exactly what's different between them - highlighted in a way that makes sense even if you've never seen code before. Perfect for comparing your live theme with a backup before publishing changes, seeing what your developer actually changed (and making sure nothing extra was modified), and checking differences between theme versions before updating.
