Commit groups sounds interesting to me. Anyone reading this familiar with Git innards? Is this doable?

You know the “group” facility of vector graphics programs? You draw a couple of shapes, you group them together, and then you can apply transformations to the entire group at once, operating on it as if it were an atomic thing. But when need arises, you can “ungroup” it and look deeper.

I’d love to see that same idea applied to Git commits. In Git, a commit group might just be a named and annotated range of commits: feature-a might be the same as 5d64b71..3db02d3. Every Git command that currently accepts commit ranges could accept group names. I envision groups to have descriptions, so that git log, git blame, etc could take –grouped or –ungrouped options and act appropriately.
