Save before merging. + +### Q: Can I see what changed before merging? +**A:** The merge dialog shows changed elements with timestamps. Future versions may add detailed diff view. + +### Q: Is merge atomic? +**A:** No. If you cancel during conflict resolution, no changes are made. Once you click "Apply Merge", the changes are applied to the current project. + +### Q: Can I merge projects from different versions? +**A:** Yes! v2.0 and v1.0 projects are automatically migrated to v3.0 before merging. + +### Q: What if two people add the same image? +**A:** If the image has the same filename and is added to different pages, both instances are kept. If added to the same location on the same page, it becomes a conflict. + +### Q: Can I programmatically merge projects? +**A:** Yes!
