Description

When I am working on a project with multiple collaborators, or when I am working on the project across multiple computers, I want to make sure that the data I am working with is the most current version. Other times, it can be hard to remember whether I pushed my data changes. One solution to this could be adding a flag to datakit data that offers the date and time of the last push and pull to this project, as well as the last user that pulled and pushed. datakit data status could work.
