When working on the same branch with multiple developers, it happens very often that a pull cannot be completed because you have some changes that are not in the source control repository. Sometimes these changes are not ready for commit, but you might need the changes from a colleague asap.
Git has the stash command, which allows you to temporally store your changes locally, so your working directory is clean, and you can pull your changes. The stash can then be applied to the updated branch.
This would allow for a cleaner workflow, less commits and therefore a cleaner history.
