If I edit a dataflow and save it, there's currently no way to go back and see previous versions of that dataflow. At a minimum it would be nice to be able to retrieve eaerlier copies of the dataflow, e.g. the source code not the data. This may look/work similar to OneDrive where I can see historical versions of a file, restore them, etc. Beyond the basic ability to view/restore old dataflow versions, other common version control features would be nice such as comparing the code, etc.
