Getting the UI right to someone who hasn't worked with branched bodies-of-work is really hard. Even in git-land you see loads of differing opinions on how best to view branches visually.

One route you might try is opinionated, simplified branching. E.g. one branch per designer, one master, daily flow is rebasing on top of master.

Kinda like this: https://gist.github.com/17twenty/6733076

Can probably get 80% of the benefits of branching without the confusion, at least, here's hoping.

As a programmer that often designs prototypes, I miss VCS branching in Figma. Are there plans to implement branches of design files, or groups of files?
