Version History/History Manager

[Suzie97]

Implementing a History Manager is crucial to the modern workflow. Almost all mainstream apps do it.

At the moment, the only idea we could come up with is to use a system based on git, and create some sort of logging system that saves the changes made to a photo in a format that can be understood by git.

This will have a lot of advantages, like someone can start a project and then share it as a git repo to someone for collaboration.

This still needs a lot of design and discussion so feel free to share your ideas.
