Tuft + Paw
very niche usage but comes in quite handy when you need it, great to find bugs while developing new theme versions
Thank you so much Tuft + Paw! We love our merchants, and if there's anything we can do to improve Diffy or give you a hand, just let us know.
Saved tons of time by comparing all theme files and automatically flag any changes. Excellent UI and would be even better if I can download the changes.
Thank you so much for the kind words! I've made a note to add a diff file download to the next version. This suggestion made may day. Most likely won't be until after BF/CM, if you have any other ideas or feedback to make Diffy even better, always feel free to reach out by email.
