+Today I built `git annex view`, and `git annex vadd` and a few related
+commands. A quick demo:

+
+Not 100% happy with the speed -- the generation of the view branch is close
+to optimal, and fast enough (unless the branch has very many matching
+files). And `vadd` can be quite fast if the view has already limited the
+total number of files to a smallish amount. But `view` has to look at every
+file's metadata, and this can take a while in a large repository. Needs indexes.
+
+It also needs integration with `git annex sync`, so the view branches
+update when files are added to the master branch, and moving files around
+inside a view and committing them does not yet update their metadata.
