If I work on branch A and suddenly need to work on branch B before being ready with a commit on branch A, I stash my changes on A, checkout B, do my work there, then checkout A and apply the stash.
If I work on A and I want to stop working for the day, should I stash my work and then apply it the next day (when I resume my work), or should I just leave things as they are—uncommitted modified files in the working directory? I don’t see why I would need to use stash in this case, except if there is some security benefit.
Also, another scenario: I work both at work and at home. If I am not ready with a commit when I want to go home, can I stash my work, push it to GitHub and then pull that stash at home?
