For starters we've made sure to make git diffs as readable as possible. The visual data is kept at the end of text file (hidden when using our editor), usually in a single line. So if you just move nodes around, one line gets changed and it is clear what to ignore when scanning the diff, while making sure to retain the changes in the repository. For later stages, we envision much deeper integrated version control, including viewing git diffs in the visual editor.

This sounds bad. Any info in the text related to the visual representation will be unreadable i guess. Hiding such for diff review is helpful but not enough. Because in merge conflict resolution one may not have the luxury to neglect it.
