Any chance you will be able to do full text diffs with Sketch 43's new file format?
Maybe by unzipping and rezipping the file before and after committing? e.g [this](http://stackoverflow.com/questions/8001663/can-git-treat-zip-files-as-directories-and-files-inside-the-zip-as-blobs). Automatic merges would be a real life changer for multi-people collaboration.
